However, when I install them in the diff case with the pinion gear, it's not so smooth. The manual doesn't call for any shims and the kit didn't seem to come with any so is it supposed to feel a little "gritty?" Also I ended up using red loctite on the set screws in the CV driveshafts did I screw up? Thanks in advance!
I have found that sometimes the diff housing halfs are over tightened, back the four long screws off and see how it feels, if it is better, just dont crank em down, after I lossened mine, i ran em "snug" looser than I would normally, and have not had any issues with them since. Hope this helps.
