Hello all. I have a problem with my W124 that's baffling me, even after consulting this group and a couple of different mechanics.

Basically, here's the problem. I have a 1993 300E with about 120,000 miles. The car is difficult to keep in a straight line at higher speeds. Also, there's a vibration under heavy braking (getting off the freeway, for example), and something just doesn't feel right about the suspension (it feels loose, mostly). Also, sometimes the steering feels wrong at low speeds -- like there's some sort of extra, "gritty" resistance. And a couple of times while creeping at low speeds (such as at a four-way stop) there's been a groaning noise from the front end. I've replaced the thrust arms and the steering dampener, figuring they'd help. They haven't really.

Over the past couple of weeks, I've taken the car to my mechanic and an alignment shop they recommend, figuring they'd be able to fix the problem. Based on the advice of this group, I had them look at ball joints, idler arm bushings, rear links, and bushings in general. The alignment shop checked all the suspension components, said everything was fine, and tweaked with the alignment. My mechanic lubricated bushings. The car felt better for a few days, but has reverted to its evil ways.

Does anyone have any more advice for me? This is getting really frustrating -- my Mercedes-Benz shouldn't drive like this. I'm about ready to take it to the dealer and hope they can find a problem, regardless of how expensive they'll be.

Thank you,
Mike McLaughlin
