Whole lotta' shakin' goin' on

yeah alignment, or suspension (shocks an stuff) or simply a bent wheel.

Most likely front-end alignment. Go to a reputable national tire company shop and have them look it over. Write down what they say. Go to a different national tire company shop, and do the same. Go to four or five. At each one, lead them to believe your interested in a full set of new tires, without actually committing to the purchase. You should be able to get them to put it up on the rack and have a look out of simple greed.

Good luck, and keep us informed. By the way, if it is the front end alignment, and its really shaking, you need to get it dealt with soon. If you have problems with the suspension, its even more critical, because as any one part of the suspension fails, it puts immediate severe stress on every other part.

A missing sway bar bushing will do it, but only on vehicles that have sway bars.

A slipped belt on a tire will too. If you get the wheels off the ground and give them a spin, this looks real neat.

Thank you very much, gentlemen. Your advice will, no doubt, permit me to sound just a bit less like an idiot when I bring my car in for service.

Well, don't get too cocky, Joe . . . never underestimate the power of a grease monkey to make a monkey out of you . . . or me . . .

Here I come with the obligatory A2k remonstrance. "You oughta get that fixed real quick"
There, noone needs to add that.
