wheel problem
 

My 300SD has a problem with the left front wheel. It makes a noise when I go over bumps, and when I turn hard right it slips and makes that screeching noise. I took it to a Tuffy for a diagnosis and they told me the groove in which the ball joint of the wheel fits is too loose, and it needs to be replaced. The problem is that the whole housing needs to be replaced when you do that, and the parts are like $700, labor $500 so it's real pricy.

I have 3 questions for you guys:
1) Is this something I can fix with a mechanically inclined friend, or do I have to take it into the shop?
2) If I can do it myself, what part of the MB CD would have instructions on that? I've looked all over it, but I can't find it.
3) Has anyone had this problem with their car? If so, how much did it end up costing?

Try a search for "ball joint", the price you were quoted sounds pretty high to me. I think many have done this type of job themselves..... might need to get a shop to do a small part of the work where a press may be needed. Good luck.

not sure if the same thing but the shop i went to quoted me around $350 to replace the lower and upper ball joint. this is with labor.

You're talking about the upper joint? The entire arm comes as an assembly. Think I got it for a click over $100......I think. I'll have to look in the books for that one.
