The two differentials where we shimmed the pinion were assembled with after-market gear sets. My new 4:11 set was of great concern to me as I knew it would not hold up with the excessive backlash and a contact pattern terminating at the crest of the pinion teeth. The differential assembled at the clinic would have worked without shimming the pinion but it was far from ideal with as many gaskets moved as possible.
The reason for my post and hosting an in-shop clinic was to get the info out there that an almost perfect fit can be obtained by shimming the pinion gear.
Good Day!
