I've been following this thread and I'm personally disgusted at what I see as a major problem with these ball joints. You see, an engineer at NCM (New Castle Machine & Forge) created the "Lube for Life" ball joint a few years ago for Chrysler. I worked in this plant on the production floor and when I heard about our plant starting a line dedicated to the production of this part, I was happy at first. This was because the LFL line was gonna save our plant from Sale/Closure in the near future as we'd also be a supplier of this joint to other manufacturers. This was of course, a lie, as the sale of our plant came to pass 2 years ago and I'm still on layoff and waiting for a transfer to another location. But I digress, I thought the LFL ball joint was a good thing...at least for a passenger car. I never thought they would have used them in offroad or heavy duty vehicles. I thought wrong I guess. I know that when I traded my 2002 Ram in for my KJ, it had a nasty habit of popping when i cut the steering wheel lock to lock upon backing outta my garage. It had LFL balls and it was the first year they tried aluminum control arms on a full sized truck (scary). I just hope I don't have these rotor and bj troubles on MY kj like I've been reading about. 8-[ (Aeh)
