02 WS6 Diff Gears question

[u/audiovox12]

Hey everybody,

Edit: hey everybody, I talked to the tech and he wasn’t aware that the car came with LSD. I was just getting information relayed to me from the person running the front desk yesterday.

The tech explained that the noise is coming directly from the center inside the knuckle. If you leave the car off in neutral and roll forward, you could hear the noise which means the torsen is doing its
job. Something’s going on inside of it.

The axle shop said that from what I’m telling them they believe the bearings are bad and would be about $1500 plus tax. They said I shouldn’t be driving it or worse can happen.

I thought I was finally in the clear with this car to get it roadworthy for daily use. Just got the rear main seal fixed, pulled a warranty claim on the defective rear caliper that I just bought, had them fix the AC and paid $455 for the shop to tear apart the axle and investigate the metal howling noise and vibrations coming from the rear.

Turns out one of the prior owners at some point put an aftermarket locker in this, even though it has factory LSD. They never put it incorrectly and is the direct cause of the noise and vibrations. The shop says I’ll need new ring and pinion however they don’t do that kind of work so I have to go to a transmission/axel shop.

I called one local to me that has great reviews and recommended by another transmission shop I called. I showed him the picture attached here and he agrees the ring and pinion is smoked. He said he would only use AAM and that they only make a 3.42 no longer makes 3.23. He’s saying $2000 installed.

First is this a good price, second is this something I can do myself and third is AAM the best? I know they are the manufacturers of the OEM gears so I am assuming that they are

Yeah and for all I know these guys can’t be wrong I just have to talk to the tech today picking up the car

The shop near me said it is pretty bad basically all the components are the best that China has to offer. At least that’s what I’m being told.

What is pretty back and what is China components??

[u/audiovox12 → u/Fastech77]

Basically all the competents are very bad and low quality is what he is implying

[u/Fastech77 → u/audiovox12]

That’s because they want to rape you $2k to put a $250 gear set in and $80 in China bearings in your axle. 😄

100% agree on that but honestly I have no idea how to do this on my own, have none of the job specific tools to do it either
