starstarstarstarstar" great part "

You can change the upper ball joint without removing the control arm. Just remove the pinch bolt and the three 10mm bolts holding the brake line.

starstarstarstarstar" Easy job to do if you have the right tools. "

I did this job by my garage. You will need a ball joint press to remove and install. It is lot easier to take the whole steering knuckle off to do the upper ball joint. If you just want to leave the steering knuckle on, you will need disconnect the front sway bar link and have somebody to pry down the lower control arm as much as you can. The ball joint press is big, bulky and heavy to control so its a lot better if you remove the steering knuckle and lay it down on the ground. Moog upper ball joints fits like a glove. Did a test drive and feels tight. Looking forward to future purchases. Many Thanks!!!
