I'm getting ready to sell my 1993 300se. Before I put it on the market I need to replace the drivers side ball joint because it's screaming. I'd like to avoid paying the bill just sell the car. I realize I'll have to spring for an alignment, but I'd rather not pay for the ball joint job. Does anyone know how big of a job this is?? Are there any little pitfalls I should lookout for??

By the way, I'm picking up my 1999 E430 tomorrow! Any suggestions on what to look out for with her?
