Broken Rear End?

[JayB12]

Posting this for a friend.

He bought a 95 tsi awd. Last night we were driving around and the rear end locked up we skided for a little bit and stopped. What happened? the brakes didn't lock up either, they are fine.

Could be the transfer case or the rear diff

Sounds like a differential issue. Where there any sounds leading up to the lock up?

 

[JayB12]

Would it be both or is it definatly one or the other? How would you tell? Not sure about the sounds, music was up too high.

jack the car up on 4 jack stands and un hook the drive shaft. turn the rear tires. if they dont move its the rear diff. if they do inspect the transfer case

We started it the other day and were able to drive it down the driveway without the wheels locking up though.

Broke off a tooth in the diff or transfercase and it got loged pull the diff cover and look at the gears.

Also another quick question... did both wheels lock up?

 

[JayB12]

The trans was rebuilt about 15k ago and we were hoping that it wasn't hurt because of this. Is there any chance we maybe did anything to the tranny? And yes, both wheels.

it might actually be the LSD. gsx's in 95 came with lsd. if the lsd were to lock up that would definitely lead to the rear wheels locking up, however im not completely sure so dont quote me

 

[JayB12]

Car does have factory lsd.

I would take off the inspection plate on the rear diff to see if there is a chunk of a tooth sitting on the bottom. You could also drain the fluid in both and see if anthing comes out of either one. If nothing comes out of either, then your down to opening them up and seeing what is going on.

this.

try to isolate the problem by actually getting the car up on stands and seeing which wheels turn with and without the driveshaft connected, which way the wheels turn, etc.
