I've got to get around to doing my front ball joints, radius arm bushings, and sway bar bushings before this spring. Local auto parts store wants about $30 each for lower grade ball joints, and about $60 each for the professional grade MOOG ones. I've used MOOG in my Dodge Stratus for Tie Rod Ends before, and they were a perfect fit, high quality. I've also heard that Ford started using MOOG ball joints in the 3rd generation explorers. I'm planning to get all my bushings / ball joints through RockAuto. I know Raybestos has good brakes, but I haven't tried any of their other products. They have the lower grade ball joints for about $8 each, and the Raybestos Professional Grade ones for about $26. The moog ones start at $38 each. I'm not planning to buy any cheap crap, like those "Auto Extra" or "Coni-Seal" ones. Has anyone used the Pro Grade Raybestos with good results? I've also noticed they carry the factory Motorcraft ones a little cheaper then the MOOG. and both the Raybesto's ones and Moog are greasable. My Factory ones are not. Thats why they're gone.
