Im installing a obx lsd in my gsr tranny and i swapped bearings and ring gear and speedo gear and when I put everything together and tighten everything down, the drive-shaft wont spin nor will the transmission shift however when i loosen the bolts the drive-shaft will spin. i did the c clip also,, i have put it together 3 times and the same thing every-time. Does anyone have any idea at all??? does something need to be trimmed down i searched and haven't found anyone with this problem,, ANY help at all would be greatly appreciated.

 

Shims, gotta check the clearance per the manual.

Hopefully you didn't ruin the bearings or crack the case.

 

What shims should i be looking at?
