I just rebuilt both my Diffs. I run putty in my front diff so it is Tight by design.
My rear diff is super free. I am running 3 shims inside and 1 or 2 outside.
Notes when building:
1. make sure the diff housing is free from all flashing(excess plastic) especially the hole where the out shaft goes
2. make sure all the gears are free from excess flashing
3.Make sure all the spider gears are fully seated down in the diff. (if you turn it with out the diff cap the gears will pop back out)
4.when putting the 2 half together don't fully tighten just one screw. tighten each screw a little at a time in a cris crossing pattern
5. use Anti wear grease when assembling if you can(if you don't have AW soak all the parts in diff fluid at least)
