Anyone using Spicer ball joints? I've had mine in for about 4 1/2 years and the lowers are worn already. A few months after I installed them I noticed the boot had ripped due to contact with the control arm on both sides. The boots were just too big. I could have just replaced the boot with a better fitting one (if I could find them sold by themselves), but I just decided to grease it more often. 4 1/2 years later and the joints are worn pretty bad. I replaced them with Moog and out of the box, the quality seems better, and the boots fit without interference. Anybody else have this experience?
