Differential stuck

[mtrx804]

So I decided to swap out my 90 rear end for a torsen. Well... It wont come loose. What am I missing?
I'm dropping the whole rear end out, the picture shows the point that it pivots but wont slide out.

It might help if you pulled the axles off the diff.

And make sure you take out the washer looking thing that one of the ppf bolts went through

The whole rear end is coming down. It is only this spot that's sticking. I might end up disassembling it all if I can't drop out the whole thing.

Yea noticed that after it was all coming down and it would wiggle there. Took it off and still acting like the washer/bolt thing is there.

On the diff swaps I've helped with, we've pulled the PPF off at the transmission and dropped the whole diff/PPF assembly. There are a couple of PPF-to-diff bolts that are a complete bitch to undo in the car.

I've done it a few times and just did mine last week by myself. And have always just pulled the axles and driveshaft and leaned the diff out of the top of the ppf and it just fell out

Pretty much what I did too.

Unbolt the axles from the stubs and remove the PPF from the trans, or all but one bolt, and swing it out of the way.

Everyone in this thread forgot about the two spline nuts that are at the top of the ppf. Thread the ppf bolts in place by just a few threads and tap the bolts upwards until the spline nuts come free. Once they are removed, the ppf will slide off of the diff.

Ahh! So there is a couple at the top too? I pulled the one from the bottom rear bolt, that's what I was hung up on before.

Ill take a look later today. Thanks for the suggestions yall. I might just drop the PPF and go from there.

Took off PPF and everything came down Thanks for the tips everyone.
So figured while i was at it I might as well change the diff fluid since who knows where this rear end has been .

What should it looks like? Drained the old one it was very dark dark and smelled like oil, drained the new one and it was clear with a blue-ish tint and smelled like silicone kinda used the same container for draining and the 2 did not mix... Thoughts?

Well different brands are going to probably have different tints to them, but the gear oil we use at work is a dark yellow tinted clear when it goes in, almost like regular motor oil. It's usually black and atrociously smelly when it comes out

It sounds like the new diff already had new oil in it.

Darn. Thats what I thought when I drained it. Oh well I guess it never hurts to change it and be sure.

Thanks for the help everyone.
