1998 4.0 XJ Classic, HP Dana 30 front, 165k miles, purchased 1 month ago. Been trying to track down grinding noise -- sounds almost like rubbing dust shield, but it isn't. Not awful loud. Can't hear with windows down or fan on high (or music playing), but noises bother me and it is there. Starts as soon as car moving and continues till 45 mph when wind and highway noises drown it out.
Noise isolated to front drivers side. All quiet on jack stands in RWD and in 4WD when drivers side wheel stationary and passenger side wheel turning. But when I block the p-side wheel so the front drivers side wheel turns, the noise is there.
Replaced driver's side unit bearing and axle u-joint but noise persists.
Differential oil was over 1" low and bunch of magnetic sludge on the screw. Haven't yet pulled the cover.
I'm guessing the only remaining culprit is the front differential. Specifically, maybe the diff bearing (side bearing?) on the drivers side since all quiet when D-Side stationary and P-Side turning.
Any suggestions besides pulling the axle and having the differential rebuilt?
Thanks for any advice.
