I have a 90 XJ with 3in lift and 31's, when i make right hand turns i hear a grinding noise coming from the passenger side front. i got a dana 30 and the faster i go the less i have to turn the wheel to hear it. i've unhooked the swaybar to see if that was the problem it wasn't, taken off the tire to look for wear marks on the passenger side suspension, checked to see if shocks bolted in now im out of ideas and fear it might be internal, i have a 4x4 posi lok on the axle and thats it.......
