First check on that chassis is the spring perch.

Mr. Dalton,
I was excited when I saw you had replied, since you always give really good info

However, I wrote the book on spring perch failure - or rather I wrote a "sticky" anyway
http://www.peachparts.com/shopforum/showthread.php?t=147997 - in short I had my perch repaired after it failed and have tried to warn others.

SO, do you think the lube would have any effect ( beside accelerating my need to replace the upper ball joint)?

NHDOC, I can feel it vibrate as it creates the crreeeeakkk when the car goes up/down in the slightest. 98% chance it's the ball joint. I DID lube the top shock mount though, but can one lube the top control arm bushings? Thanks for the reply, though.

About 4 years ago, my car creaked when I would drive over speed bumps and ramps. Took the car to my mechanic and he used WD40 to lubricate all the bushings in the front. He used 1-2 cans. It worked like a charm. Even to this day, there are no creaks.

The most common cause of creaks up front is the sway bar end links and bushings, but that would not be easily confused with the upper ball joints since these are down at the bottom end of the suspension.

MB only sells the upper CA with the ball joint as an assembly. I have heard on other models that people have successfully been able to replace the ball joints on them but the whole arm is only $150-$200 or so therefore usually it is cost effective to just replace the entire arm assembly.
