Kinda looks like the spider gear shim washers, and the color of the fluid on them looks as bad. Likely the diff is done.

Yep, those go behind the spider gears, I found the same thing on a 6mt I bought to swap in. Bummer..

On the subject of clunking when warmed up, my problem is persisting after replacing the center differential, it seems like it might be the rear differential so I'm replacing it next week.

After the c diff replacement I jacked up a single rear wheel after a long drive and turned the wheel while in neutral. The result was a very difficult to turn wheel that would pop and release l like the diff was binding, once it cooled off it was easy to turn again.

Also when the warmed up while driving, locking up the brakes on the snow (abs fuse yanked) there is an awful grinding noise. I'm hoping this is also the rear diff as one wheel stops rotating first.

I'll let you all know how it turns out, getting tired of fixing this old clunker!

So I've replaced the center and rear differentials and as far as I can tell I do not have any binding anymore.

The problem I can't figure out is when I brake on snow and lock up tires there is an awful grinding noise, it sounds like it is coming from the transmission. The center diff is freshly installed out of a 2013 WRX.

I can't figure out what this is! Does anyone else experience this horrible grinding when breaking on slippery surfaces? It's much more obvious when I pull the abs fuse.

Thanks!
