Those that have rebuilt their read diff, I'm installing an evo8 diff into my 1g case. I'm using the very smallest shims of the kit and still can't install the diff with both shims. The only thing I can think of is the new bearings aren't pressed on enough but they look and feel like they're pressed all the way. I verified this by comparing them to my 3 bolt diff sitting around. Any thoughts?

Measure the total length of each to see if they are the same/similar in numbers.

I'm not sure what you mean, but I measured each shim in the kit and used the two thinnest shims and still can't get the diff in.

Measure to the millimeter the total length of the diff that you removed and the new one that's going in end to end.

I’ll do that but it’s considered equivalent to the Dsm diff in size.

I think I figured it out. I still have the evo ring gear on...

I'm asking you to do this to see if the bearings are all the way on the diff.

Is the evo rear much stronger?

It makes the rear end more aggressive when turning.

Its stronger and you go to a clutch type diff. The advantage of this diff is you can induce over steer with the car instead of under steer. This is caused by the clutch locking the rear diff. It made a huge difference on my vr4.

Are you by chance using my write up on the install? The evo ring gear wont work. Different gear ratio.

I'm referencing your writeup but I happened to miss that part. I'm trying again today. Thanks.

Hmm, I just realized that I am indeed using my dsm ring gear....now I'm stumped.

Maybe I need to switch the top plate of the diff as well. I need to do some more reading.

It turns I already had the dsm gear on..it's been a couple months since I last messed with this project. I even tried the dsm diff top (?) and it's still too wide for any of my shims. Totally lost.

Are you using the dsm bearings or Evo bearings? Also while installing try to rotate the pinion. I noticed that was holding me up.
