Wasnt trying to freak ya out just pointing out the OV, normally you can tell there really shot by the popping they normally but not always make. and like someone said check the tie rod ends and bushings while down there they all make the suspension as a whole and like i said before its plenty worth it to buy the bushings and whatever else you need and get it all done at once since you have to tear the suspension apart to get to the ball joints, i actually took the bar as i am going to call it that holds the ball joint in ( i dont know the tech name for it off hand ) and put it in a vice and beat the hell outta the ball joint being very carefull not to bend anything, worked out pretty well, ill be doing the same on my 89 maybe this weekend, we have a miracle in Southern California today IT RAINED!!!!!! so dont know if ill get to do mine this weekend.

Good Luck
