MOOG Suspension Ball Joint

I've ruined several brands of upper ball joints. Price alone doesn't seem to be a guide to quality. There are two general designs for these ball joints: Ball inserted and crimped into place from the bottom or from the top. If the top is smooth, it was inserted from the bottom, which is a weak design which will fail offroad.These Moog ball joints are the better design, with the ball-stud assembly inserted from above and the retaining crimp-ring on top. That means that the ball-stud assembly doesn't put leverage on the crimp ring that distorts it, which is what causes failure in the other design.If you drive hard offroad, you can expect several years of service from these ball joints. If you stay on the pavement, I can't imagine them failing in your lifetime; these are seriously strong.

Moog ball joint, obviously good. I didn't use it though, sold the truck and returned it. Advanced Auto Parts was awesome the whole way through. Bought online, painless pickup at the store, rented a press tool, also painless. Didn't need the stuff anymore, returned it, all quick, no hassle and great customer service.

I installed this and found that the rubber boot doesn't cover the joint when it is at a mid to high angle, leaving the joint exposed to corrosion and debris.
