Great work. Vw wouldnt touch that because it couldn't be repaired by spinning on a filter. What you guys do is true mechanics. Brilliant, keep it up. Your apprentices are very lucky to work with you guys👍👍

I learned a lot from your video👍 Ended up taking the diff off my self and took it apart. The smaller bearing on the right side was completely worn out. The bigger bearing on the left side was still in good shape, but replaced both bearings. That’s was the easy part. My problems started when assembling, and I ended up taken it to a mechanic. Shims were too big, and when we tried to fit the housing, it was almost impossible to rotate the shaft. New shims are almost impossible to find. The mechanic took the shims to a specialist, and he took off 0,2mm, on the right side shim. The diff has been running for a year now, and everything is good. Thanks for an informative thread and video. Greetings from Denmark 🇩🇰

Noice fix. The dealers only want to replace today as they make more money and don't have to warranty the work if the part fails. Good to see a real mechanic figure it out, offer the customer a better cheaper fix.

AWESOME!! I just purchased a used 2017 Alltrack and was on the VWVortex site and discovered a bunch of people with this issue, I’m experiencing the soft grinding sound that gets louder when I decelerate on my passenger side (U.S model). I’m scheduled to visit my local VW dealership on Monday as the car is a CPO. I know their gonna try to give me the run around (breaks, rotors, diff fluid change etc…) I’m gonna show them this video now 👍

@sp19822 3 жыл бұрын

You would think they would offer a rebuild kit with all the bearings and bits required, rather than force someone to spend $7000 on a complete new unit. Great work saving that diff, and a lot of cash as well.

Hello. are any additional special tools needed? is it necessary to adjust the tooth clearance when replacing the bearings? what should be the play between the teeth? I can cover up. or maybe the way with a piece of paper is enough? I have a problem because it hums from 60km / h and there is a radial play on the left joint that goes into diff. (on the bearing in the middle) will the replacement of the bearings help? . I have a lot of background and skills, but I'm a bit afraid 😁

Hello, thanks really for this video, I have to do the same on haldex 5 for octavia scout , but I don't find any video to remove the haldex from the car (there are 2 bolts with access by the top so it seems mandatory to remove rear axle? And for the rebuild after changes of bearings is there any setting/measure to do ? thanks a lot for your help

@vjlau02 Жыл бұрын

Hi, you are correct, either you remove the rear axle, or you can drill 2 holes inside the truck and you get access to the 2 screw you mentioned. Done the same operation some 2y ago. Hope this information helps. Just google, haldex removal, holes inside trunk etc.

Great video! In my car also (golf alltrack 2017), the noise increases when decelerating. Initially I thought they were tires or wheel bearings, but after replacing the noise still remained ;/ Do you think that the cause of noise in my car may be the same as in your car? Thanks for any tip!

I got a 2015 Audi S3 and has a noise like you made. I changed my wheel bearings and rotors only to find out it's a bearing on the diff. So far, I've had no luck finding anyone that rebuilds these rear diffs. All shops say they need to replace the whole carrier assembly. I have not seen any schematics to find the bearing part number

The number are in these comments below , but they may not all be the same. Full dismantal then to see if you can find them. [i spent a long time finding them] and couldn't get one seal.

I currently have the diff out sitting with my mechanic ready to be pulled apart, but if I can pre-order the bearings for him it would be fantastic.
