I was reading somewhere that sometimes a slight bend or taper is built into spindles to give a little bit of camber. Is that true with our trucks? That means they could be clocked to change camber and caster slightly. In fact, I don't think that I've ever made it a point to put them on in any certain orientation. My camber (front) is slightly positive and I think that perhaps it is supposed to be. The drivers side a little more than the passengers side, which I've heard helps you track better on a crowned road. That may be fine for skinny stock tires, but I want to maximize the treadwear of my pricier tires by setting camber to 0. I have been planning on buying some shims to go between the knuckle and spindle, but wondered if anyone had any other ideas. BTW, ball joints are good and tight and wheel bearings are set correctly. I have considered an offset ball joint adjuster. Is there any advantage to them over shims, because clearly they are harder to install.
