Hi! I have a 2000 XJ on a 3 inch lift, and I get grinding/vibes when doing about 50, but if i turn right, such as in a corner, the vibes go almost completely away. Any theories?

It would have to be something which is effected by the turn such as wheel bearings or axle shaft u joints.....I'm betting it's the u joints. Unless the the vibe and the noise are coming from the rear which I would think would be the diff do you have a factory locker?

JeepaholicNinja

Definitely coming from the front. No locker. I had thought maybe it was from the very slight distance change between t-case and diff when turning, but then I realized the whole axle and diff don't actually move left and right. It's just the tires and joints on the axle ends, right?

Probably the u- joints...Idk. No idea when they were last changed but the jeep ha 197,000+ on it haha

U-joints maybe, ball joints a little more likely, hub bearings too maybe

Mine was very similar, it was the right side unit bearing.

Thanks guys...sounds like it could be a lot of things haha. I'll have to get it off the ground and wiggle stuff till i find something loose haha

could also be tire balance or tread wear pattern

A wheel bearing going bad will often heat up. Using an infra red temp gun after cruising on the highway is an easy way to possibly pinpoint issues. Look for elevated temps compared to other side.
