“Use of an impact wrench during installation; tapered surfaces contaminated with oil or grease; application of excessively high torque would pull the tapered portion of the ball joint too far into the steering knuckle. The sealing boot is too taut on the joint and twists in this area with each rotary movement until the sealing bellows suffer a fatigue fracture. As a result, the joint corrodes and causes noises.”

I had the front passenger airmatic strut replaced in June ($1100.00). But now the driver's side ball joint is squeaking. The MB service writer told me the joints really can't serviced, just replaced... I felt like they just needed greasing (that's the sound they were making). But I was told (on here and at the dealer) that there are no grease fittings on the W211. (stupid, if ya ask me).
It's been squeaking for about two weeks now. And I'm leery of getting them (both joints, both sides) replaced, for fear they'll start squeaking again......
I'm tempted to slide the boot back and slap some #4 heavy lube grease on it and see what happens. But I know I'm not.....

MB mostly has joints that can be replaced without replacing the whole control arm.
Is your worn joint the upper or the lower one, or one of the others?
Materials, lubrication or sizing will cause these issues. Just too many on this board complaining about ball joints for me to believe there is not a design issue of some type.
Ball joints are waaaaay down the list of maintenance items. Its rare to say the least.
You guys need to get your hands dirty and crawl under your cars more often. If anything just to see if **** was replaced. Could save you thousands. I check the oil after each change just to make sure the guy getting "flagged" hours really did my $200 oil change. Trust no one.
