Hey guys, I need your input here. I "shimmed my diffs" last week while I had my truck apart. While taking the diffs apart I saw that one of the diff rings was pretty hammered, so I bought a new pinion/ring for that diff. I installed both tonight and noticed that there is some binding going on in both diffs. After messing around with shims, it seems that they bind a little no matter what I do. I've inspected them thoroughly for burrs and they're clean. I cleaned the diff housings, so I know all the bearings are seating perfectly. Any ideas??
(I checked the side to side movement from the output shafts and they were tight...no need to shim yet)
