Not sure why, but I decided it would be a good idea to swap out my rear end gears myself. Right now, I have the new pinion in, with a new bearing and the old shim. From what I read, you re-use the old shims, which is what I’m doing. I have that set and it’s “rotational Force” or whatever it’s called is around 20 inch pounds. When I try to set the carrier in, I can get that in with the old carrier shims just fine, but I can’t spin the pinion or carrier anymore. Am I missing anything? Thanks

My credo
In theory, theory and practice are the same. In practice, they are different.
Did you say "new pinion?"

Your carrier shims might need to change in order to put the ring bearing in the right place. It sounds like your ring gear is too far to the right and is jammed up against the pinion. Pinion depth also plays into this. So, once you get the carrier shims adjusted to put the ring gear in the right place, you still might have to re-work the pinion shim to get the pinion depth right for proper tooth engagement. Did you measure pinion depth before you tore everything apart?

I did measure everything before I took it out. I don’t know why but I forgot that I’d probably have to shim it side to side. The pinion shim looks good so far, already checked it with paint and the pattern looks good. Thanks for the response

Either your pinion depth or backlash is too tight, and it has the gears locked up.

You need to go back and check your pinion depth, and make sure you didn't flip your carrier shims.

In your new pinion gear or bearing are not exactly the same as the old ones your pinion depth is going to be off.

Yes. He mentioned that. He called it "rotational force".

Good enough
Making yourself a "set-up bearing" with a new, spare pinion bearing is recommended for this process.. It'll save you some trouble.
