Well I know that it is coming up time to change out some ball joints and all on my truck. I have already done the drivers side ball joints but not the passenger side. Recently it has started riding extremely rough, especially when going around a left curve. If I am driving down the highway, it will clear up after a mile or 2 and ride smooth until I stop again. I am wondering if maybe my brake caliper is sticking? This is the only logical thing I can think of that would make it ride rough sometimes and not others. Advice? Thanks!
