I have 02 GMC pick up not 4wd and I’m changing the rear diff my came with a 3.41 I’m put a 3.73. And I tried everything to get my pattern to change for the pinion marking is high on the heel on the drive side and low on the toe on the coast side. I move the shims up I move the shims down. Nothing works please help
