I am finally setting up my m20 on my 76 cj5 I have gear lash set at between 006 and 007 this still seems like a lot ? as I turn the pinion there is a lot of noise if I dont keep constant pressure while turning pinion with ratchet is this normal? I dont have any oil on gears yet , I checked contact pattern which was tricky no pattern at first until I put wrench on ring gear bolt while turning pinion to apply resistance and pattern actually looks pretty good load and coast for first attempt set up using stock thickness shims
