I have an intermittent "grinding" noise and sensation which seems to come from the front end when slowing to a stop. The transfer case has been rebuilt, the front u-joints replaced, the pads and rotors replaced, and we can find no problem with the wheel bearings. The front end was realigned when I replaced all four tires and no problems were found. The transfer case engages and disengages smoothly, I just got back from a week in Moab and the San Rafael Swell where we did some trails that I didn't think the Ranger could handle. No problems but the annoying noise. My mechanic threw in the towel, the dealer wanted to charge me $750 to replace the locking hubs. Since the Edge doesn't HAVE locking hubs I decided I didn't want that shop touching my truck. Any ideas?
