Charles. At the Build School, they really emphasized the importance of getting grease to the faces of all those large suspension bushings. Helps the suspension work properly and not bind. It's a little time-consuming, but you will notice that INSIDE the bushings, there are grease channels molded in. Simply use a Dremel with a cut-off wheel to extend those channels out (like a star pattern) across the faces of the bushings. I found it easiest to put the bushings in a vise and then just grind away. Takes thirty or forty seconds per bushing. When finished, it will allow the grease you pump into the zerk fitting to travel to ALL the bearing surfaces of the bushing - not just the inside ones. Don't know how many other guys are doing this... ERIC
