Earlier today i was doing an oil change on my truck and for the hell of it i decided to do the rear end as well. While waiting the diff to drain, i shook the shocks for the hell of it and to my amazement, but mounts that "were" welded to the frame have broken off clean. So on monday in going to grind the frame and reweld them unless someone has a differnt idea for what to do. This now explains why on the highway with a few hundred pounds in the bed the truck bounces corner to corner. This happen to anyone else?
