Rear rotors which were only 35,000 miles old wore out. At the same time the axle seal was failing so at least it called attention by the grinding before the rear end went dry and would have blown. Brakes again, what can I say but these trucks have very undersized and badly designed brakes which undoubtedly will need attention regularly.

Plan on replacing pads and usually resurfacing rotors every other year. Buy the best but not the hardest brake pads you can get and KEEP AN EYE ON THEM. Doing that will get decent service and not cost you too much. Get aftermarket parts, way cheaper and quality has to be better than the Jeep OEM stuff. Don't wait too long and let them get too far worn down and they won't usually cost you much beyond a set of pads to fix.
