Ok the trucks in my signature. I seem to go through alot of needle bearings in the front hubs. I have replaced both hubs and have been replacing the needle bearings with the NAPA kind. Seems like everytime i pull a hub off there is alot of metal dust in there. The stub shafts are new on both sides as well as the u-joints. Im starting to think i have a bent axle shaft or something. Maybe the inner axle bearings?
