How do you know if a front end problem is worn bushings or worn ball joints? I've got 206,000 on my '92 240. Original everything up front. When I back out of a parking space and turn the wheel, I can hear a clunk coming from the driver's side. Not really loud, but noticeable. Recently, I've begun hearing a slight clunk when I turn (mainly left) at low speeds. Also, there is some abnormal wear on the driver's side front tire, along the outside edge of the rubber.
I'm willing to bet the bushings are all shot...but how do I know if the ball joints are bad, too? And is there any way to tell if its the lower or upper ball joint making trouble? I don't have a lot of money on my hands these days, so I'm only replacing things that HAVE to be replaced. Thanks!
