I recently had a mechanic give me the dire warning that my lower ball joints in front were worn out, and that I should replace them at a cost of approximately 350 dollars. the consequences he said were that the wheel could fold itself under the car, causing catastrophic damage if I were travelling at high speed. I got this same prediction from another mechanic, but both shops were chain shops (midas and brake stop, respectively) that were trying to sell me expensive brake jobs (which I eventually did myself. howto with photos to be posted soon). how concerned should I be about this problem, considering I'm looking to be out of the car within 6 months? After I get a new car (probably an ES300) I'm going to hold on to my mercedes and probably use it as a project car. Also, is this a repair I can do myself?
TIA
