hey all, forgot to add this up last week. i replaced all 4 ball joints. i used this video to help me through the process so instead of trying to record my own i thought i would just share this one. hope it helps you. F150 Squeaky Ball Joint Replacement - YouTube
thanks iowa. i thought the bottom ball joints were much harder to do than that. that video makes it look much easier. the uppeer ball joint/contol arm is easy to install. i had mine done in about an hour or less. i will say that my arm did not come off as easy as the parts in the video did lol. i beat the hell out of the arm and it took a while to pop the joint out of the knuckle with the pickle fork. one thing i wish i would have done when i put the new arm on was install them eccentric cams for alignment. might have to this summer.
