Default Torsen: A Love Story. Is this the end? (It was the bearing)









So I am getting poping/clunking under initial acell and decell as well as left turns. Pretty sure it is shot

Try new axles first? Could be cv's.

It's a type 1 Torsen though. I don't see how the bolt axles could be the issue when the slack is in the drive shaft and diff. Idk I'll check though

Backlash needs to be adjusted. Was this a torsen swap?

Factory Torsen. I put the ebrake up and I put it in reverse and I can twist the rear wheel slightly. Like there is a little play. Tonight I'm going to look at the axles.

You have slack in the wheels with the e-brake set?

(I'm trying to imagine how this is even possible.)

Seriously and the e brake is super tight. It will lock up the rear if I pull it.

That's why I'm posting vids cause if I just said it yall would think I was crazy

I drained the diff fluid. Ran a magnet through it and didn't find anything. I'm starting to think this is a wheel bearing possible

The hub bearing has failed and is at least one of your problems. The diff still seems to have too much slack though from your video.

The bearing was separated. I didn't even need a press to get it out I could use a flat top and I tapped the bearing out.

THe whole bearing or just the inner races? The inner races pop out of the rear wheel bearings pretty easily.

Sorry I was posting from my phone and the mobile app was giving me issues. Also the hub has absolutely no cracks and is not warped. I will replace it anyway though


The bearing was still together but the inner sections were separated separated. What do y'all think about the diff slack? I have a feeling I will have to measure the backlash if that could be avoided that would be great. I hate pulling the diff


EDIT: Would this be considered a valid guide for me to correct the backlash? This seems like and easy solution as long as nothing in the diff is severely damaged

Thanks for changing the title though that has not been confirmed as the entire issue with all that back lash

Does the pinion have some sort of support in the case (i.e. bushing/bearing) that could be worn enough to cause excessive backlash or other movement? I've never torn into one, so I don't have any idea.

There is also a crush washer, that preloads the pinion.
