i have a frind with a stock 99 xj sport. he's had his carrier bearings in both the front and rear axles replaced as well as his rear pinion bearings. he doesn't wheel in fact its his wife's vehicle. has anyone else had problems? i have a 99 classic and have never had probs and i wheel mine...is this just a random thing or are we missing something?

SOunds very random, unless the wife is doin some hardcore burnouts in the grocerry store parking lot.

i haven't heard of anybody else having these kinds of problems. i told him i'd help him swap them out for a couple of 44's while we throw on a 4" lift for his wife. he laughed but his honey didn't. oh well. it'll take some time but she'll break...we hope.
