It could very well be the trunion bearings. I bet they are just shot, when i take turns it sounds like the tire is being dragged and chirps the front tires. But this is the same on both sides...my iroks got warn pretty bad, the tread from the out side to the inner is at leased an 1/8" difference. I need to just tear it apart and check it out. What sucks is its my DD an i work all week
