99 XJ (box stock) with 42k miles. Started hearing 1: a low speed grinding noise from the front, 2: a slight vibration when turning at 30- 40 mph and 3: a "clunk" when slowly backing up and turning the wheel. (like when backing out of a parking space - happens only in reversa and either when turning left or right)
After doing some reading on this forum, I concluded that the most likely suspects were front wheel bearings / u-joints. I tore into it last weekend and sure enough, the bearings were shot (one had rust leaking around the rear seals) and each of the u-joints had one or more dry bearing cups. (Advice to anyone thinking about trying this - go look at the axel replacement write up on MADXJ.COM - excellent stuff).
Anyway, the grinding and vibration when turning are gone but the darn "clunk" when turning while backing up is still there! I gave the front end a through greasing and that didn't help and I'm totally out of ideas. Any suggestions??? TIA.
