Thank you so much for this video and your guide. My local dealer wanted $567 dollars for this same job that you did on this video, I was able to do it under 45 minutes and for about $60 dollars. God bless you and your family.

This is the next best thing to hanging out all day in a Toyota Service Dept

I don't think you know how helpful you are to so many people. Thank you.

You do a great job teaching and providing correct fluids and torque values. Fantastic lighting and camera work as well. No questions unanswered as you anticipated all issues and helped prevent others. I wish all tutorials were as thorough.

A simple ‘thank you’. The correct information from a highly qualified and respected source. Needless to say, as soon as I get OEM Washers I’ll be picking up the oil(s). Now onto your fluids video to determine what oil I need for my 2017 Tacoma SR5 4WD with limited slip….

i like how you always take so much pride in your work as you always clean extra fluid up right away. We need more people like yourself AMD to work on our Toyota cars and trucks

Even though I had watched your video before I forgot about the 'hammer tapping' trick. I tried to remove the fill plug on my 2016 Highlander's differential with a ratchet (no go) then an impact (again no go). I watched this video again and tried the 'hammer tapping' and both of those plugs came out SOOOOO easily with just a ratchet!! Thank you so much for the tip, you saved me a bunch of money! Now, I just have to find the fill plug on the transfer case LOL.

I learned a lot about Toyota vehicles by watching your video. Real genuine Toyota information.

One of the most important elements of your videos.. is going slowly and being calm. People that are new to working on cars can get nervous and rush thru things and make mistakes. Your thinking thru things is a great thing to teach. I many years ago did a clutch / press plate / pilot bearing on a 280 z datsun. I made the mistake that you covered. I forgot to loosten the fill plug until I had the transmission back in the car.. my mistake clearly. I ended up filling the gear lube thru the speedo cable hole with the back of the car up 5 feet.. a huge project. I told the owner... my girlfriend that the car is good.. but if we ever pull out the trans or clutch I need to address that fill plug. She never had anyone ever check the level in 15 years of ownership ☹

Thank you for making informative videos that you provide. Even though I may not try some of these procedures on my own ( too old: lol ) I still find that watching and learning how things are done is always a good thing thanks to people like you showing all of us how and spending your time creating them. Thanks again.

Very informative and explains why I was unable to find my daughters front diff drain/fill plugs in her AWD Sienna a few months ago!! (But I got her TC and rear Diff changed as well as the transmission) For those crush washers, we put the side with the crease towards the vehicle, smooth side on the plug.

Thanks Ahmed! I'm getting ready to change the rear diff fluid on our 2008 Highlander with 250,000 miles on it and wanted to make sure I watched you do it first! Being in Massachusetts, I've been underneath the vehicle recently to observe what things look like after all these New England winters - that diff is crusted over with rust! I'm so glad to have seen you tap the plugs with a hammer, great tip!! Thanks again for the effort you expend for all of us DIYers.

Just did the transfer case & front/rear diff service on my Dad's 2017 SR5 Crewmax 4WD Tundra last week! Ordered via that Ravenol Gear Oil kit. I reused the washers because it was the 1st time for this service but will replace for sure next time now that I know the part numbers. Thanks AMD.

Cool. I have a 2006 matrix 4wd with 183k. I use a 24mm 12pt box end (fill plug) and a 24mm 1/2 drive socket (drain plug) for transfer case. I ground the chamfer off the end of socket so it grabs the low profile bolt head better. Very easy service with proper information you have given.

Thanks again for showing us DIY warriors how to properly service and maintain our vehicles these how to videos are much-needed and appreciated 🙏🙏🙏

Your contribution to the DIY community is immeasurable. The amount of detail you show within each instructional video is far superior compared to anything I have seen out there. God bless you for the work you do. Subscribed. Do you mind clarifying for the 2017 Highlander XLE how many different crush washers/gaskets are there for the front, middle, and rear gear oil fill and drain plugs/bolts. I want to make sure I am ordering the right parts. Thank you in advance for your time.

Great video! Your approach transcends just car maintenance - it celebrates quality in all we do.

Glad you mentioned the warning about the “smell”. Differential fluid can be an extremely repulsive smell to some people and lingers for a long time if spilled… Not like I know first-hand or anything 😊

Really enjoy your educational style of videos and recommending it to friends. At time mark 10:40, about cleanup from oil on the exhaust. I actually throw a plastic or silicone pad over the pipe before cracking open the fill and drains to keep oil off the pipe. Cleanup goes much easier.

Your videos always impress me . Really great explanations for DIY and for people that may not do it but it’s good for them to know the process and all that’s involved . You and everyone at your shop are just incredible . You guys blow my mind

Great vid. Just changed the diffs and transfer case fluid on my 02 Sequoia. The tapping must work. All drain and fill plugs came right out. 😊

AMD you have the best tutorial. I did mine 2019 Tundra with Schaffer moly synthetic gear lube. Incredibly increases MpG to 17 from 15. Dealer wanted $600.

I called my local Toyota Dealer for a quote on my 2019 Rav4 Adventure (Torque Vectoring) just out of curiosity: $400 for rear diff, $300 for transfer case. OMG, are they freaking kidding!!! I'm doing both for about $100 in about an hour plus I'll have washers and the syringe for the next change. Thanks for the video AMD!

Thank you for this video sir. I didn't realize how easy it was to change differential and transfer case. It looks easier than changing engine oil. My dealer was charging me 400 bucks to do this job.

Thanks for educating us. Knowing the 'why' is always important.

Thank you so much for this high level of transparency, openness & teaching.....

A great educational video on draining and refilling your fluids. Very useful.

You saved my bacon with the hammer trick. Some penetrating oil overnight and some hammering on the front diff drain plug got it loose. I had tried a long cheater and even an impact without success previously. Last person to tighten it was the local Toyota tech. An Arizona 4Runner without a speck of rust.

I changed the differential fluid today in my wife’s Lexus. I crawled under from the rear as far as I could and used a mirror tilted toward the plugs to show me where to put the hex drive socket and also where to insert the fill hose into the fill hole. The mirror made it easy, without having to raise the vehicle.

I went to my Lexus dealer and requested them to change these fluids at 32,000 miles on my 2020 Lexus IS300 AWD Sport. They said they don't do these fluid changes as they are lifetime. Never had a dealer turn down a request for service before. I may have to try this myself using this video as it sounds like it should be done. Thanks.

Thanks. I'm gaining confidence i can do these maintenance jobs by your fine demos.

Great videos!! I’ve watched a few of your videos and this is my first comment. You always teach me at least a few things every video! I appreciate your honesty and as always, thanks for sharing your knowledge!

I never thought about opening the fill before drain…great advice !

"We are car care nuts here, we're doing this ourselves" has a good ring to it.

Nice, concise video on a very necessary service! Thanks for the efforts in making it.

Great review and helpful hints for the do it yourself person. I know you are very busy with your shop but it would be nice if you did a series of maintenance service for the third generation Tacoma. You really explain things very nicely. Thanks

What about checking the breathers on Toyota Transfer Cases and Differentials. Where are they located? When I worked as a diesel truck mechanic (retired now) when doing a regular engine oil change and service, you always checked the Transmission and Differential breathers to make sure they were open and not plugged up with dirt. A plugged breather will allow the unit to build up pressure (from the heat) and push oil out a seal. I've seen guys change a leaking Wheel or Pinion Seal only to have it leak again because the breather was plugged. Also when servicing drive train components, the vehicle must be level so that the fill plugs work correctly. A vehicle that has one end up on jack stands is likely going to give you an incorrect reading on the amount of oil you installed. Not everybody has a vehicle lift in their garage. Thank you for taking the time to make these videos. There is a lot of information available and you do a great job explaining everything. Best regards Gerald

Nice work brother keep up the good work I really like how you work and care about the car like it's yours I wish every mechanic like you thanks so much .

I own two Toyotas, This guy is a treasure.

Thank you for giving us the torque specifications i really recommend using a torque wrench on drain and fill plugs.

Hey AMD, love your work thank you. A suggestion I work at night and listen to your recorded live stream. You can upload just a audio version of your live stream on podcast which will be very helpful in expanding your reach. I want this channel to grow. Thanks again 🙏.

I am so happy i found this video. I had my highlander transmission replaced and when i got it it started to leak transfer case fluid through the weep hole, only when i drove it. I took it back to the shop and the technician checked the fluid but i noticed the fluid gushed out and at that time i didnt know it should not gush out like that. They said there was no leak and it was a little normal to have som seepage in that area because they recently serviced it. But i noticed it kept leaking it was just small leak but i wasnt very happy about it. I started looking for answers and found this video, i remembered i saw a lot of oil comin out when that tech showed me that it was ok on oil level, and i went to check myself after watching this video, and sure it was overfilled with fluid. Thank you sir for this video it really helped me. I will look forward to see if it doesnt leak again, but im pretty sure it wont.

I have used this opportunity to swap the upper fill plugs with magnet style as well. And upgrade to 75w-140 synthetic.

Great tip brother on the removing of the fill plug always before the drain plug

Great tip on the taps with a hammer. My plugs were rusted quite a bit more than the ones in this video. I didn’t have penetrating fluid so I used some brake cleaner after using a #mall wire brush. Before doing these things I couldn’t budge the fill plug. Afterwards it was as easy as if the plug had already been loosened half a turn. My Highlander has 125,000 km on it. The dealership’s Service Assistant manager told me last year Toyota has no recommendation for when to change these fluids. I us3d 75W90 Royal Purple synthetic gear oil and a1.5 litre ( about a US quart and a half ) syringe type of fluid transfer pump. It worked flawlessly, no leaking no mess. The plugs look way bigger on here than they did when I changed the diff.

Really good walkthrough from start to finish-thank you!!

Very detailed explanation just as open book. Thank you so much for the video posted

Would you do a video on towing capacity breaking everything down from a mechanic's view , love your videos you don't discriminate you tell it as it is and are not afraid to tell us the good and the ugly.

Thanks! Very helpful. Especially the labor one can expect if hiring it done.

You and your info and vids are literally the best. Thanks.

The best videos EVER on Toyotas.

EXCELLENT tutorial, sir!! Thank you for sharing your expert knowledge and educating weekend warriors like myself! :) God bless!

This is great this just came up. I’m changing these fluids tomorrow.

Thank you. Your teaching technic is very informative and clear. You should be a professor at a technical school/ university😁I’m sure the students will learn from you a lot! -Los. Keep up the good work.

Thanks for this video. I was on my way to filling from the high-mounted plug, until you set me straight!

Straightforward and direct instructions. Thanks!

thanks. you answered multiple questions. I'm used to normal 4wd

Thanks for another awesome sharing mate. Super appreciate it.

As always, great video. Thank you AMD.

Thank you for the vid. Just Bought '11 RX350 FWD with 29K miles Lexus and want to do fluid cleanse.

Outstanding video. Very informative…. Keep up the great videos! I will send you a sombrero !

As always an excellent informative video. Thank you

'98 LS400. Most important thing for me was being sure I could remove the filler plug (very tight) before removing the drain. Had to order the exactly right gear oil (Miller's). Both Mobile and Lexus of NA advised that I not substitute a similar multi-viscosity product. Substitution for LS430 was OK. Probably shouldn't have done the job since the old oil even after 140K looked great and no debris at all on the magnet.

On my 4Runner I replaced the factory transfer case drain plug with a magnetic one. The size is M18x1.5×12. I used a Dimple Motor Oil Magnet but there are a few others on the market.

Another nice and simple DIY instruction, complete with part numbers and torque specs. It would be nice to have some input on the breather valves, regarding any cleaning, testing for blockages/rust, or pre-emptive replacement since they are a common cause of oil seal leaks in the rust belt.

Thank you for the valuable information it was awesome!!! 👍🏻

Great video CCN! I have a 2010 Rav4 AWD and wanted to know what oil to use in the Transfer case as well as the rear differential? Thanks for all of your helpful video's you post. Much appreciated!

My local dealer charges $450 for this as a “4 Wheel Drive Service.” Using this channel and others, I was able to do it for $75-including synthetic gear oil and new gaskets-on my 2005 Land Cruiser. Thanks you!

Another thumbs up from me🤟🤓 have a great day.

This guy is an absolute legend! Thankyou for sharing your information once again. I have a quick question, is the Mobil 1 better than genuine toyota gear oil?

awesome another topic I was wondering about 👍🏽👍🏽👍🏽👍🏽.. thank you very much

Thank you for such a helpful video 👍👍God bless 🙌🙌

Thanks for sharing this video, interesting and informative, thanks

Just did this on my 2014 Toyota Rav4 which has 75000 miles on it but the most difficult and time consuming part was taking those stubborn hex bolts off (certainly a couple taps didn't work for me lol... I live in Toronto so am not sure if the salt on the roads during the winter creates this condition)especially the fill-in plug which is so hard to get to that i almost gave up. The transfer case/gear oil didn't look too bad (light brownish) so i don't know if it was worth the hassle since it's synthetic. I had recently replaced the transmission fluid after watching your video and that seemed so much easier. I can take comfort knowing that I don't need to worry about it for some time now😄 and thank you🙏🏽

Such great videos! You’re a great teacher!

Another great video. Thanks for posting.

This video was very helpful and this is definitely something anyone can do. A couple of tips based on my experience with this is: 1. If you are skinny you can do it without even jacking the car up. 2: No idea how he got a ratchet in there as I had to use a 1/2 inch drive ratchet for the 24mm socket and while I could get onto the bolt, I couldn't ratchet as the exhaust pipe was in the way even with a swivel head. I ended up just adding a bunch of extensions (I saw this in someone else's video showing how to do this) and that allowed the ratchet to be all the way back behind the black floor shield and gave it room to move without rubbing on anything. From back here you can also see much better 3: I ordered a fluid pump but got the wrong size for my container and had to improvise. Using a large fluid syringe it was also pretty easy to put it in (especially for the rear diff). 4: Mine took exactly what the manual states for a 19 Highlander - 0.8qts in the front and 0.5qts in the rear. 5: There is a random hole on the left side of the rear of the transfer case (appears to be for a stud of some sort?). Going in blind after having been out from under the car for awhile and with the refill bolt out, it is easy to confuse the two if you are just sticking your hand up there to feel for a hole. If you do make this mistake, the oil will just seep out right away from the stud hole and if you are using a pump it will likely make a big mess. The best way to get visibility is to go back behind the black floor shield as you can see the refill hole very well from there. Whether using a syringe with an extended hose or a pump, i would suggest you set it up and then pump from back there so you can see everything you are doing.

This is a great straight forward procedure for those tackling it and a refresher for those of us who only do it once every 2-3 years! Are the procedures for the AWD Torsen models any different?

Thanks so much for these videos. I really appreciate them as they help me better understand my vehicle. I have a question. I have a Toyota Corolla Axio 2010 AWD and I recently noticed a noise which I thought was due to worn out bearings. However, I have later found out that the noise actually originates from the rare diff. My thoughts are that I replace the entire diff... Challenge with replacing is where to find a replacement? And is this still a good idea because alternative is to disconnect the drive shaft and convert the car to a 2WD. Would you recommend that?

I enjoy your videos immensely and even though I don’t own a Toyota vehicle I will eventually as they are so well built and reliable. I apologize if my question has already been answered, but to do this maintenance doesn’t the vehicle need to be level like when servicing the transmission fluid? Thank you so much for your expert service to all of us.

For the 24 mm plugs on landcruisers etc, I have a six point socket that I have ground the open face flat to eliminate the champher - lets it engage with the skinny plug a bit better.

Excellent video as always!

Great hands on video 👍🏼

Thanks for another great tutorial! You make it enjoyable to work on your own vehicle!!

First, thank you for all of your videos, I was able to solve my own issue with my 4Runner (below) but I also have a 2015 Tundra Platinum and need help based on something you mention to be aware of. You mention that the TUNDRA transfer case drain plug changed in SOME year models, 2014 and up, where the seal is built-in and the drain plug must be replaced and part obtained from a dealership. My problem is that of two dealerships that I have inquired with, NO ONE at the parts desk can answer my question thus far if my drain plug is one of those. My local dealer identified the correct part on their computer diagram in front of me but it must be ordered (a week to arrive, after selling me the wrong drain plug initially) but still told me that he cannot tell me whether or not the plug is of the type you mention with the built-in seal. My transfer case drain plug is one that sits flush (not a hex head) and it is driven by a 3/8" square socket drive extension. Are you able to tell if mine is one of those design changes? I do have my 4Runner for use, but my Tundra is on jack stands now until the new drain plug arrives, unless I use the old one which I am not inclined to do. When I removed my current drain plug and fluid, there was no washer on the plug.

Can you talk about cleaning the vent on top of rear differential to prevent pressure build up and seal leaking. great video's

Thank you very much for this excellent video.

Love all your videos. So much info

Hello, thank you so much for showing us. You are an awesome teacher! I have 2013 Toyota Venza. I could not find the differential drain plug anywhere. Please advise. Thank you in advance!

You, sir, are an inspiration. Your hard work, dedication, and attention to detail are 2nd to none. This is a great channel. What are your thoughts on the 2017 Lexus CT200h ? Thanks so much for your feedback.

Awesome video as always!

Does it matter which way you orient the crush washer

Thanks for the video, I’m laying in my gravel driveway changing the transfer case fluid today. Could you do a video about approved jacking spots on the Sienna? I had to Jack the rear up at the differential but I’m not sure it’s the greatest spot.

Back when I was married(!) I bought my wife a 2001 Sequoia. I changed the rear differential oil at 10,000 miles. The drained oil was dark gray and had lots of metal shavings in it. My next change was at 30,000 miles. It was much less discolored. At each differential oil change the oil looked cleaner and cleaner. I guess my last change was at 120,000 miles. That oil looked like I put it in the day before. It was that clean after 30,000 miles. I did all maintenance by the book and we never did have any problem with that vehicle which appears to be typical for a Toyota.

Great video you are my Toyota mechanic

Thanks so much...short and informative.

Hi. I love your videos. They help me a lot. Can you tell me why you used mobile 1 upfront and Valvoline in the back? Can you put the oil with the ls additive in the transfer case as well. I didn’t know if I should do it or not. I would like to use the valvoline for both front and back. I have a 2016 Highlander xle awd.

Great video. Thanks

Lexus GS/IS/LS Sedans have a rear AWD transfer case that shares fluid with the trans. The trucks I believe have their own Fluid. Clean out your vents too. I had a front axle seal leak on my GS and it was because of a clogged vent. Similar setup to many trucks.

Its an important consideration to level your rig when its in the air while doing this.
