Anybody rebuild any of these. Have had mine for 4yrs now and have worked awesome, but while fixing my high steer I pulled my axles and found drivers side ox joint wobbly. Basically a couple of the brass bushings are worn. Has anyone pulled these bushings before? I have lost a couple side caps one time (forgot thread lock) and I called them up and sent me the parts for free!!!! From florida I think it was. Im hoping they are as generous with the bushings. Im hoping these are not a pain to get out. The side cap threads are really close to the bushing edge, if that makes sense?
