    Default Alignment Shop Must Be Wacky.

    Had the alignment on my 87 T-Bird checked today and the readings the Shop gave me are wacky and the reason they gave me for these values was the ball joints were bad and they wanted $450 to do the repair.

    Readings were:
    Camber L = -4.2 deg Cross Camber = -7.2 deg Camber R = +3.0 deg
    Caster L = +2.1 deg Cross Caster = +0.5 deg Caster R = +1.6 deg
    Toe L = +1.55 deg Cross Toe = +1.28 deg Toe R = -0.27 deg

    The last alignment readings from a different Shop were:
    Camber L = -1.6 deg Cross Camber = +0.4 deg Camber R = -2.0 deg
    Caster L = +0.6 deg Cross Caster = +0.1 deg Caster R = +0.5 deg
    Toe L = -0.39 deg Cross Toe = -0.81 deg Toe R = -0.41 deg

    On the right front Camber I don't even think it is possible to get a +3.0 deg reading without having the car damaged in some way. Reason for the recheck was new front springs were installed and the car was pulling to the left slightly. The new springs did raise the front end a little. I'm not worried about the Camber reading because I don't believe those are accurate. My question is going by the Toe readings from today would those readings result in the car to pulling to the left? As for possible bad ball joints I'll check them myself before relying on what this Shop said.

    wow, those specs look nasty. ( i do alignments )

    your camber being so far out on the left side is causing your pull to the left.

    I will say that a bad set of ball joints could cause the specs to be so far out. I would check them, both for in/out movement, and for up/down movement, using a bar, while supporting the lower control arm. I would have asked the shop to show you the play in the ball joints, any reputable shop will gladly show you the bad parts, as a way to verify they arent trying to screw you over. At least that's how it is here. I gladly welcome to show my customers why im suggesting that they let me put in parts.

    Take it to another shop and have them check it. Do nothing other than ask for an alignment check and then compare the results.

    Could someone explain how toe in can vary from side to side??? Is this spec taken with steering wheel straight ahead??

    Traveling down the road IF there is say 1* on left & 0* on right, it will divide itself out to * on each side, yes the steering wheel will be slightly off center...






    My other rides (that actually do run & drive)

    total toe is what you explained, where 1 degree on one isde and 0 degree on the other would divide itself , and the steering wheel would compensate by being off.

    but the reason that toe looks off more on one side vs the other is that most alignments require a caster sweep, where you turn the steering 10 degrees to the left, 10 degrees to the right, and then center it from those specs. most modern machines use triangulation to measure how much needs to be taken out of each side.

    Thank you

    So basically it finds a possible mis centering of steering wheel?
