    Just got my alignment, have some questions, please help

    Some history-- before I got my car, it was in a collision involving the R front side. I know this because the R front fender has been replaced (no VIN) and the front valance on that side is damaged. The trunk is original so it probably wasn't THAT bad.

    Anyway, I've noticed that the R tire wears out on the inner edge faster than the L tire (more neg camber). Since there was a collision there, I attributed it to that. So I went to a Firestone service shop (I know, I know...) to ask about the alignment, and they said that they'll lift the car and if they see anything bent or physically damaged, they'd tell me about it and not charge anything. If everything was okay, they'd do the alignment. I figured it was $50, so why not. I understand that they're trying to make $$, so maybe they wouldn't be completely honest, but a large branch like that can't be completely dishonest.

    When they lifted the car, they inspected the suspension and said nothing was wrong. I've taken a look at it before, I've never seen anything obviously wrong either (but I'm no expert). So they went along with the alignment. Here are some notable specs that I got. They only worked on the front, as their printout instructions told them that.

    Left:
    camber -1.3 (specified range -1.2,-0.2)
    caster 6.4 (8.0,9.0)
    toe -0.04 changed to +0.13 (0.11,0.19)

    Right (ranges same as left)
    camber -2.1
    caster 6.2
    toe -0.03 changed to +0.14

    Their computer printout instructed them not to mess with the camber or caster in the front or anything in the rear, so they didn't (and rightfully so). All they really did was increase the toe in to spec.

    Anyway, my main question is that the R front camber was WAY off (-2.1). I understand that they can't fix it, but doesn't this mean that there WAS some structural damage to the suspension parts? Is there another way the camber could be so far off? I know some people like running camber that high (low?), but I'd at least like both sides to be equal.

    Also, should I even care that the caster values are a bit low?

    One more thing: I've heard that zero toe is ideal, so why do the specs say to align to positive values like that?

    Thanks.

    zero toe is ideal for turn in, etc, but also increases tramlining and would reduce the driving experience for your mom, i like zero toe, but thats just me.

    you could have multiple things wrong here, bent strut, tweaked frame, bad control arm....

    my money would be on strut or control arm unless they hit something super hard

      The control arm looks good. I've inspected that several times. How badly would the strut have to be bent for it to reduce the camber like this? Would it be obvious to the average eye?

        You know oddly enough my alignment specs were about the same for my car when I had the last alignment. I can't see anything noticeably bent and I replaced the control arms last year.
        My car was also in a front end collision at low speeds but I am pretty certain it was put on the frame machine to check it out and all was well.
        I may start with a new strut and go from there.

          What I want to know is if I should buy a camber correction kit for only one side so R and L are more similar to each other. Or should I just let it go?

            unless you are into replacing new parts completley on the injured side these cars will never be perfect again.Then you will find out it was a body problem to start with. Tires are cheaper than pursuring a problem which may never be fixed.Unless you have a modern rack with very specific measurments-forget it.I worked at a shop where they made the racks- the specs were better than stock amazing. The racks were relatively small also-Awesome

              could be a bent control arm or strut. they wouldn't neccesarily be able to tell just by looking at it.

                I'm not ready to replace the control arms or struts, but I guess I'll find out when that time comes. But back to my original question-- is it possible for the camber on one side to get so far out of spec (-2.1) without something being bent or broken? Or is that a clear indiction (given the accident) that something is off?)

                Anyway, you guys don't think it's a good idea to get a strut tower bearing for camber correction? +/-0.5 degrees.

                  you could do it but it's kindof a bandaid solution, and you'd be paying for the same amount of labor anyway. for your camber to be that much different, yes something has to be bent. could be the frame, could be the suspension - you'll have to figure that out though. control arms are fairly cheap though and you should be able to find a good used strut for almost nothing.

                    I didn't realize those strut tower bearings required labor. I figured that they just bolted on top of the strut towers without the need to lift the car.

                    Anyway, you're right, it is just a bandaid solution. But I don't want to randomly replace things to see what's wrong. I'll see if I can give it a more thorough inspection for now.
