This is confusing everyone. YOU CAN'T TELL SOMEONE HOW MANY SHIMS THEIR DIFF REQUIRES. Every diff is different. That is why they send out shims! If they were the same for every diff then they would tell you how to put it together in the manual! Some will require 2 on one side and 1 one the opposite or the other way around. Some might only need one on each side.

If you have questions about shimming diffs email me at [email protected] and I'll try to explain how to do it.
