At 125,000 I had the Pilot bearing START to sieze. I pulled the the truck apart and decided that since I had it apart to put a clutch in it, although I could not see anything wrong. The clutch, flywheel and pressure plate all looked like new. That new clutch chattered like mad, so I put another new one in. It also chatters. So in 25,000 miles I have installed 2 new clutches. My question, has anybody ever broke a motor mount on one of these trucks? The two dealers in my area do not even stock them. There is no call for them. They look like they are bullet proof! Is it possible that I broke one. My truck is STOCK!
