Re: TJ intermittent vibration question...butt tickler.
I wouldn't think you'd need a SYE because A) it's only 2.5" of lift and you have the t-case spacers B) you didn't (knowingly) change the pinion angle and it worked fine before.
You say you put in a 4.10 geared axle, was this a complete axle you bought and bolted in? What's it from? Custom made or stock? Get an angle finder and check the pinion and t-case angles.If the control arm mounts are positioned just a little different than the other axle's were, the pinion angle could be off. It could also be a slight tweak to a tube on the axle you bought. Or a tire worn a little uneven that was put on the opposite side during all the work. Lot's of possible causes, I just learned to live with my slight vibe that comes in from 65-75, but that's running on unbalanced 35" mtr's.
