I do understand that moving the pinion is very different than moving the ring gear. The point I was asking about was if moving the pinion forward (away from the ring gear) would influence the pattern change in some similar ways as moving the ring gear away from the pinion. I understand that they are doing different things, just wondering if the movement of the pattern was similar.

I already have the spacer and shims in there. And I use a pry bar to put some load on the mesh.

Thank you and I appreciate the tips. I have done this several times before. It's just been a while and then some of this info I never knew at all.

I'll pull the pinion tomorrow.
