I have been trying to track down a suspension or drivetrain issue in WJ 4.7 2"BB for a couple of weeks now. I've replaced the axle shaft, bearing hub assembly and this past weekend I have been working on replacing the ball joints in the passenger front wheel.
After I finally removed the old ball joints, and managed to squeeze the new ones in, I got the lower ball joint to line up well with the knuckle and was able to get it to where it should be. The upper ball joint is a different story. I cannot really get the knuckle to line up right at top. As I attempt to tighten up the nut, the bolt inside the ball joint turns too. Not always though, it just seems that there is enough pressure that it ends up moving which I find very odd to begin with. Why isn't it staying and allowing me to tighten up the nut? What can I do? Is the new upper ball joint defective? Why won't the knuckle line up as it did before? Is there a particular procedure for this? I was so close to being done and I am pretty confident that the ball joints were the issue. I really want to get my Jeep back on the road and home so I can do more work on it.
Your feedback is greatly appreciated!
