I think I see where they are going with this, let's see: How bad is it
pulling? Is the wheel straight, and it drifts to one side, or do you
have to hold the wheel at a noticeable angle to keep it straight. If its
the latter, your car may be doing what is called dog-tracking. Basically
going down the road sideways. Imagine the rear wheels being on a
different "track" than the front wheels, so you have to hold the
steering wheel to the side so both wheels are going straight ahead.
Thats called a thrust angle alignment, which should be included in a
four wheel alignment. My car does this, but it hit a curb at a lot
higher speed than you probably did (about 30-40 mph, sideways, breaking
the front axle, and bending the rear, probably pushed it to the left an
inch or so). Your problem could be as simple as a bent tie-rod or a
little more, a bent control arm. You say the shop said there is only one
alignment adjustment for the probe, maybe they dont know there are 2. On
the front the toe angle (toe-in/toe-out) is adjustable, as well as the
camber. The toe is adjustable by turning the tie rod ends on the tie
rod, and the camber is adjustable by turning the strut mount on the top
of the strut, or by loosening the strut to steering knuckle bolts and
pulling or pushing on the strut or knuckle to get the desired camber
angle. I dont think the caster is adjustable from the factory, and
shouldn't have to be. (could change from accident damage, though)
They are right about the frame straightening if its actually bent, but
if you ran up on a curb its more likely to be a suspension piece thats
bent. You then have two choices, either take it to another shop (make
sure they are good, Butler Tire if youre in the Atlanta area) for a
second opinion, or have the car put on a frame straightener to see if
the body dimensions are within specifications. I guess I should have
asked this first, did it do that before you took it there? Well, Fred,
hope that wasn't too long. :) Let us know what you find out.
P.S. Could you post the alignment specs they gave you (should have
before and after numbers) after they finished?
