Thank you!! Idk why other videos say it's so hard and takes so long!!

I appreciate it! I ended up going to college so I didn't have the funds for car projects anymore. Maybe someday I'll make a comeback!

Isaias Lopez Thank you I'm glad I could help!!

jamaicanbullet Thank you!!

I have been trying to make a video for what feels like years. My life flipped pretty quick after making this video. I've been trying to come out with a video explaining the situation. I really do appreciate the feedback!

Tbh I don't remember 😅 I don't think I did.

I can try to help! Fist off when do you notice the noise? Is it metallic sounding, grinding, or just sounds like air? There is no carrier bearing the drive shaft is one pice self supported.

Do you hear it with the fan off?

Hey thank you for your reply guys, appreciate that. Well to say it sounded like air...kind of a whirling sound. It is this sound, may be a good idea to turn up the volume. Here is a video from another KZfaq account kzfaq.info/get/bejne/qJaontagudzZfXk.html This happened id say with the last couple months, not that it is getting worse...hope not. Maybe you guys can help make the call? Thank you very much in advance!

Sprydo7 I have honestly never heard that sound before. I would have to be there in person to pinpoint where the sound was coming from. At this point it's guessing. It could be simple like air filter, belts, or oil change in the engine and transmission. I would have a friend go around and under your car to find where the sound is coming from.

Everything is steel.

@@LifeonWheels thanks

A torque wrench measure the force put on to a bolt or nut. It is important but not necessary. It is to make sure that the bolt or nut won't come loose when you are driving. If you have done suspension parts and haven't had issues with stuff coming loose you should be fine. But I would recommend getting and looking up torque wrenches to add to your collection of tools! I hope this helps you out!!

Thx for replying, i did some research and mostly you can go without the wrench but the problem is that you can overtighten the bolt

@@HOMEP_1 I've personality never had an issue with over tightening bolts. I have had bolts fall out from under tightening. For me the torque wrench is just peace of mind especially when pushing a car to it's limits!

It's called its a business with overhead and employees to pay. Fuck wrestling around doing this on a gravel driveway

Sorry for taking longer than normal getting back to you! Wheel hop like you said is one major sign. Another like what you are experiencing is a "thudding" between shifts, you should hear it coming from the rear end. I still had goo in my bushings but the diff it self was hitting the sub frame causing the thudding between shifts and coming back onto power hard. I do believe new diff bushing will help and do it soon. Mine was so bad it broke the lsd so I was doing one tire fires. You will also notice in corners (with the new bushings) the car wont be as tail happy and should fell more solid. You might not notice it now because you got use to how it feels but that was one thing I noticed after installing them. Good luck!!

No worries, thanks so much for the response!! I will be replacing all 3 diff bushings this weekend, Im glad you clarified all those things because I was nervous about doing this whole install and have it not be my issue, Im experiencing the diff hitting the subframe currently, so definitely going get it taken care of this weekend, thanks so much for your help and the very informative video. I would definitely be mad if I broke my diff !!!! Now Im nervous, how did it break the diff?

No problem! I can"t say for sure how it happened because I did drive the car hard and drifted it around. I am sure it was a contributing factor. With the torque input into the diff and it being loose from the bad bushings, it would twist putting more stress on the axes and making them harder to turn. In return it put a lot of un-necessary stress on the gear set. That's just my hypothesis, it also could be the previous owners drove it just as hard as I did and something had to give. I would also check your u joints on the drive shaft to make sure they didn't flat spot because of that. With the extra give in the diff it could be a possibility, it happened on my car. In that case the whole drive shaft would have to be replaced because it has non serviceable u joints, but luckily there are good deals on ebay for low mile drive shafts for the z's if that is the case.

Well, I haven't been really beating on it, and had to flick it sideways once to ensure, this morning, that the diff is functional ! These bushings are going in this weekend, thanks so much for your help !!

I did. Once you take the shafts out It will start leaking all over. If you are digging this far into the rear end, It would be a good time to replace the gear oil in the diff.

Hold up I'm wrong. I got confused with another car I worked on recently. The 350z drive shaft and axles are bolted to flanges on the diff. You do NOT have to. It would make it lighter if you do it the way I did.

I haven't had any issue with it yet! I can't remember if the instructions said what the grease was to be used on or not but it works that's all I care about 😂

Hahah yep true that, im literally half way though mine now, then onto the front end. Cheers 4 the vid

Zach Dillon Have you tried hammering them out after burning them? If that doesn't work you may need to take it to a shop to press them out. This usually won't cost over $30 to have that done. If you have a hydraulic press available I would use that. Another way is to take a drill and a saw to it like the carriage bushings. Let me know how it goes!

I used a 36mm socket and a hammer just be patient

Daily_g35 I had the same issues to! I also had tire hop! After doing this the tire hop went away but I was only doing one tire fire. I believe my lsd went out due to the twisting of the diff.

Life on Wheels oh okay 🤔

@@papi_zz3490 you have an open diff homie buy an lsd

@@gerardoalarcon9043 my base model 1 tire fires, I'm *open* to suggestions

@@hackdeez1075 weld the diff or put a aftermarket lsd in it the oem lsds are trash

If those are whiteline bushings, you put them in upside down and the grease in the wrong spot. The bushings have part numbers. Put them in correctly

About 6-7 hours. That's with messing around trying to burn the bushing on the diff off, eating and figuring out tools and the process. So with a good understanding and the tools I used I think about 5 hours.

I wish I could. I haven't released a video or statement about the status of the car till now. I sold my 350z for a Focus RS a few years back. I am now in school for engineering so most of my time is dedicated to that instead of video editing. Otherwise these bushing made a noticeable difference I think in handling over yeah worn out factory bushings!

Life on Wheels thanks for that and hope you are doing well

@@daskamu No problem! I hope you are safe and healthy! Stay tuned for more content. I have a lot of videos recorded that I need to edit!

Thank you!! To bad you couldn't join the fun lol

Don Bremmer I'm such a kid at heart 😂

TopSecretVid RIGHT!!! luckly I haven't replaced that yet... But I will when I replace the transmission... Another thing that pisses me off that they couldn't make better synchros!!! So now you know another video that will be coming down the pipeline 😂😂

Life on Wheels and the wheel click when going in reverse..lol...and the cover material for the interior trim bits..ha

TopSecretVid haven't gotten wheel click but I have painted my interior bits lol

They are Whiteline bushings. They are designed so they don't have to be pressed in like the oem ones. Also they are solid polyurethane so they are stiffer than oem.

@@LifeonWheels well that is what Im ordering. Its not $ thing but $130 for a single use tool? Nope!

@@Dragandspinn what tool are you talking about?

@@LifeonWheels the bushing tool from Z1

@@Dragandspinn I remember that tool now 😂 yea you dont need it but would make it easier!

You work with what you have lol. But ive had an h3 hummer on jack stands for 3 months and never had an issue. And plus I do a shake test every few hours if I have to work under a car to check stability. Not the best set up to work on cars but it works!

I get ya

some of us dont have a choice

You do what you gotta do but definitely make sure it's stable and shake the crap out of it. I lifted a 90's model Lumina off my neighbors face doing the same thing.

TopSecretVid From the wise words of boostedboys "fuck it" lol. Ik it could cause damage to the boots but after my inspection I did not find any. And it was only like that for 4 hours now more than a day I would of.
