i just replaced the whole halfshaft on both sides twice on each side in the last 10 months

, so i know that thoses are fine, corey checked out every thing up front when he did the allignment and tightened up the ball joint, but i hear the noise again, im not sure how it is got loose in the first place, but its gettin annoying, it was the other ball joint that i replaced last june not this one, the noise starte when i was going over some rough terain (mud bogin type stuff), ill check out the bushings and stabilizers tonight or tomorow, im not feelin to well today, but i might later tonite, how can i tell if it is the ball jount or bushings and such, not real fimmiliar with that stuff yet, more with the motors and interior aspects, thanx
