since my truck was new Ive always had alot of slop in the steering when under a load. I had an alignment and it helped but I noticed my cam bolts are maxed out with neg caster. I now have 315s and it seems to have gotten worse. Dealer says they cant find anything wrong but they have not put a load on it yet. They also tell me the cam bolts are ok to be set at max. My Q is what if i really do need more caster but they cannot set it any higher. anybody else have drivability issues under a load?

Thanks,
Jerry
