Aloha, I'm finally to the point of installing the new diff in my 89 TR and I'm setting it up to test the preload. Just to get a starting point, I installed a shim behind the LHS cover bearing cup that was the same size as the one that came out. I also used the same shim under the RHS cover. The crown gear is not installed. I have 3/16" play! That's huge! This diff is flopping around in there with that much side to side movement. I thought I might have to re shim this whole thing but that's a lot of room to make up. Has anyone else had this experience when replacing the LHS cover and installing a new diff? I know I'm not missing any parts so I assume either this side cover is much shorter or the diff is.
