I had the front end aligned about a years ago. Had the front end checked out at a local MB Indie shop. They said it needed a new idler arm bushing. I replaced that. No change. Problem still comes and goes. The last couple of days it has been really bad. Could this be an issue with power steering pump or steering box issue?

Everything's on-the-table here. I'd have everything checked out by a front-end expert / shop. I would definitely not drive on, or at highway speeds though, until I did.

this is usually a case of worn subframe bushings in rear, - the forward ones of the set. The entire subframe actually does move slightly as the links move with the wheel, thats why MB did not bolt it tight to the car.

The bushings make sure the subframe returns back to position, if they are broken internally the movement will steer the car.

I have been there once in a W124 - now need to do it on my W210 - same setup as W124 at the rear.

Its a 5-10 cuss per side job provided you are experienced on working/mcgyvering tools to work such problems.

to test the bushings - take a screwdriver/prybar etc and lever the subframe from the rear wheel wells, if it moves easily they are shot., similar for all other links, any torn bushing requires replacement.
