Hey man - thanks for this video. Got this exact issue on my sorento and I’ve been babying it til I can get to the shop.

Good video... cheers from Portugal!👍

My sorento is currently having this replaced on it at dealer. Good Video

Would a brand new one of these sitting outside of the car spin both sides simultaneously? I bought a new one on ebay and when I spin one side the other side spins to is this normal?

It is happening on my santa fe as well :( What is the reason for binding? It looks like there is no much that can go wrong inside? Pressure sensor?

my 2014 Santa Fe v6 is making a thud when starting from a complete stop while turning, it will do it up to 3 times when not going completely straight from a stop. There is a used car warranty on the vehicle so took it to the toyota dealer where i bought it and they could not get it to do it, yet can hear and feel it and so can my mother. The toyota dealer took it to the Hyundai dealer and hyundai tech also said there is nothing wrong. They had the car for over two weeks between the two dealers! This video may help my case. was this vehicle you were working on make that clunk, thud, whatever you want to call it?

My palisade 2022 in australia is getting this coupler replaced. It used to give thud/ shuddering on tight turns. I am not sure if i understand what is causing that shuddering but it will be replaced

Hi there,how can I change the oil in coupling unit please on a kia sportage 2011 awd?many thanks

Good video. Any idea how much fluid goes in the coupling and what kinda fluid it uses. I’m going to assume low viscosity atf.

Hi. What torque for 32 Bolt?

Please the spanner you use to remove the big nut on the flange size

Thinking about weld this two members together and pot an end once and for all to this problem. What do you think?

thanks for sharing and the info

Is this system the Haldex awd?

Merci pour cette fonctionnalité

interesting. i have a 2012 tucson that came up with a coupler pump circuit open code. no drivability issues but the car is essentially only front wheel drive atm. will be taking it in soon to inspect it. there’s actually a tsb on them where they want you to replace the pump and the harness. we’ll see how it goes

Got 2011 Kia sportage automatic transmission I start to have the same issue when I start turning and accelerating.. few months later it dose the same (back skipping or losing traction and when the car shifts to gear2- 3-4 on ward it’s transfers the bang or clonk to front left (can it be because of front transfer case ? As it starts at the back when starting to drive which is AWD is on than later front left means two wheels drive., that’s why I’m assuming it’s the front transfer case Plz advise buddy Thank you

saludos amigo también aplica para la kia k2700 ? muchas gracias..... Greetings friend, does this also apply to the Kia K2700? thank you so much

Good vedio. Came to a stop and took off and a bang noise came in the back on my Hyundai kona 1.6T. Awd. It only happened once and everything ok now . I don't no wy it happened only 1 time.

Found out, Redline MT-LV 70W/75W GL-4 is the oil.

Can you advise on the type of oil to be used for filling the coupler after potential repair? Thanks.

How much oil came out of it? You had no codes in the 4 drive error code

Hi i have sorento 2023 8k code p195800 tells me to change 4WD COUPLING ACTUATOR ASSEMBLY REPLACEMENT what happens if i will leave it with light on dash . and no torque in rear wheels!! any problems if i ignore it? thanks

I have to replace this on my telluride. Any chance you have a video on how to pull this unit and install a replacement?

when you get a new one since there non servicable do they come with oil in them i would think . surely it doesnt pump the rear end fluid or gear oil from the differential in there

The repair manual recommends resetting the ECU using GDS tool after coupler replacement. is there a DIY method and if not, what would happen if it's not reset? Thanks.

Thank you

2012 Kia sportage here, rear wheels weren't spinning in snow even with the AWD lock, took it into Kia for servicing and they're saying I need to replace the Rear Diff 4WD hydraulic actuator, not a cheap fix, any ideas on what else to look out for?

Interesting. Thx Jeremy 👍 Ps: How did you get the cutaway for the thumb nail?

Does it needs to change hydraulic fluid? How is it possible to change hydraulic fluid? Do i need to complete disassembly it like you on video?

I have a 2016 Kia Sorento AWD and I asked the KIA tech about changing the oil in the differential and transfer case. He said they both were factory sealed and couldn't ever be changed???

Hi Jeremy I have a 2010 Kia sportage 2.0 crdi AWD, it is permanently locked on 4wd, please let me know how I can permanently get it defaulted to 2wd only

Hi, the only maintenance for this AWD system is to change the oil of the differential right? Like the haldex on VAG cars ?

I have a 2006 Tucson I'm wondering if this is the same thing they use in it. Whenever I enable 4wd sometimes the back wheels will lock up even when I reverse. I only can run it in 2wd at the moment.

Hey... question... what fluid do they use... and is there a place to see how much fluid it needs? I have a 2010 santa fe Awd ... I'd like to try to rebuild it.. it's binding..

Sabes donde puedo encontrar el sello que retiene el aceite, no tengo el numero de parte y no puedo encontrarlo en internet

What typle of oil gets put into this mini pump area? ATF?

Hey , thanks for the vedio, i have a question, I have kia sorento 4WD 2015 have a issues when turning car keft of right gives pooping sound. I am having this issue for couple of years, niw dealer says that it needs to replace couplings assembly. What do you advise Thanks Najeeb

Hi. I have a Sportage 2013 and when I turn left or right I can hear a boom boom sound coming from the back. What part do I need to change? The full casing with all the parts ? Thanks

Hello. After driving an hour there is a banging sound when i stop and go. My question is can i disabel the awd?

Just curious, can the 4wd coupling be removed and use the different without it? Would it basically make the difference a posi?

Changed mine and now the all wheel drive light is on. It’s wasnot before. Any suggestions?

How to take care of this awd coupling? I Have Palisade awd and has been change this coupling under warranty, so can you share how to take care of this Part? Because Im worry this part gonna be fail again someday.

hello my friend please I need know type hydraulic this and how much ml liter .. thanks.

What makes it roll in park?

Great video. I believe that's what's gone on my Santa Fe as well. The other day I accelerated from a red light and I heard a clunk around the rear end of the car. I noticed it would stop passed 50 km/h driving straight. It was bad during takeoffs from red lights or stop signs, or while going left/right. Since I was away from home, I asked a mechanic to remove the drive shaft and the noise stopped completely. This makes my AWD car a FWD one, at least until I can get it fixed. My question is this: does my issue sound related to the 4wd coupling? I also noticed, when they removed the drive shaft (the shaft that goes from the front diff all the way to the rear diff) that there was a oily wet spot under the 4wd coupling. Is it possible the clunky problem is related to the leak, aka to the loss of pressure within the coupling?

so i take it uses the gear oil in the rear end i made the mistake of changing my rear end gear oil i just used snythitic gear oil well it didnt take long for this to start sliping so i bought the limited slip gear oil what a big differnce only splips or jerk once in awhile i know after i replace this coupler i will always use valvoline synthitic limited slip gear oil

Ciao all'interno che olio ci va? Il livello si fa dal tappo a brugola?

What if you remove the clutch's & weld the shaft permanently?

Are these a common problem with Hyundai and Kia SUV vehicles.

Hello, I watched your video "2016 sorento 4wd coupling replacement” Great work, thank you. Curios if you might have any insight to my situation. I replaced the AWD coupling part number 47800 3B520 on my son's Kia Sportage EX. Unfortunately I did not notice that the electrical connection on the new coupling oil pump has three pins compared to two on the old coupling oil pump. I also ordered a new wire harness part number 47891 3B310 but that also has two pins. Do you know of a newer wire harness that might work? Or can I swap the oil pump from the old coupling to the new coupling? They look identical.

Nice informative video but please, please, please get a tripod or a magnetic camera mount. I cannot watch all the wobbly video, it makes me feel sick. Sorry!

question (from Sweden) I have a Kia Sorento 2011 automatic transmission (crdi) and also no 4wd. My symptoms were when I put it in reverse and turned it sounded like the splines were not engaging and the sound was quite loud. Wasn't 4wd locked. And the car was only front-wheel drive. And the sound was heard as it came from the rear axle. I have also seen on KZfaq that it is common for the front transfer case to have problems with the splines rusting and being destroyed. But am pretty sure it came from the rear axle. Is it likely from my description that it is so🤔 And how can you determine if it is the differential. Thanks in advance❗If anyone can confirm my teroi on this.

Hey buddy, your video says that you are going to show us how the coupler works. You did not show that. You are showing what parts are inside. Plus, you are so confused by talking and talking that you are swallowing the ands of the words..... Your video will be good if someone wants to rebuild the coupler and not to see how it works.... Sorry, don't take it as insult. I am just trying to help you understand what you are missing in your video.
