this does not happen in 2X4. not sure if it is the axle or what.
while in 4X4 there is a grinding or clunking type sound from the right front. on 2003 Jeep Liberty
Sounds like a transfer case problem or u-joint issue. Betting on the 4x4 transfer case.
I agree with cb30 the axle and hub or bearing doesn't change in any way from 2 or 4 wheel drive! Only the transfer case and front drive shaft. You the jeepfixer so you tell me what it is. LOL!
