    I can only seem to find the alignment specs for the GenII.
    Does anyone know if they changed for the GenIII?

    Rrolf, The camber figures you gave are for the rear suspension but your post doesn't specify that. Front camber is adjustable with Toyota parts, front toe is a standard adjustment, rear camber and toe are adjustable with aftermarket, but not Toyota parts.

    In case anyone is wondering, the rough road package increases ground clearance. I believe that is the standard suspension in Australia and a few other countries with lots of rough back roads.


    Stealing your post and adding and shamelessly editing....

    Thanks - one of those things I've never played with is alignment - so while I get the angles. I've got no real practical knowledge......

    Nicely done :)

    Now if you can explain how I can check my to-in at home............

    Thanks guys. the place i have my lifetime alignment with does not have the 2010 specs yet. They can manually enter them though so I'll give them the above.

    Just curious: are you getting alignment checked just to verify it's on spec.? I know MSantos recommends this.

    I have mine checked and adjusted every 15k miles. For me that's every 9 months or so.

    Today I'm getting new wheels and Tires (40k Miles) so I'm having them confirm alignment.

    OK, trying to decipher the above.
    I'm not sure what i'm looking at.

    Is there an acceptable range value for toe, camber and caster?
    on the 04-09 prius it was:
    Front suspension acceptable ranges:
    Camber: -1.3° 0.2°
    Caster: 2.4° 3.9°
    Toe: -0.10° 0.10°

    Cross Camber: -0.8° 0.8°
    Cross Caster: -0.8° 0.8°
    Total Toe: -0.20° 0.20°


    Rear suspension acceptable ranges:
    Camber: -2.0° -1.0°
    Toe: 0.03° 0.28°

    Cross Camber: -0.5° 0.5°
    Total Toe: 0.5° 0.55°

    You can do a good version of the B-A method at home.

    Jack you car up and spin each front tire. As it is spinning (slow is OK), hold something steady against the tread to mark it as it spins. Magic marker, scribe, soft pencil, it doesn't matter as long as you can see the mark. Some people just measure to the grooves in the tire tread, but that's not as accurate.

    Roll the car to a stop on a level surface. A garage floor is usually good enough. You roll it instead of using the brakes because the brakes change toe a bit.

    Measure the distance between the lines on the rear of the front tires as high up as you can get a straight shot at them. Then measure between the lines in the front. You will need to compensate for the fact that you couldn't get all the way up to axle height with some trig.

    Here's another way
    Adjusting Toe-in Using Tape Measures

    This one shows scribing the tires but also uses paint, I haven't had to use paint.

    Just had our 2010 at the dealership for the 20,000 service. They also did a 4 wheel alignment for about $80, but I believed that it didn't need one as it wasn't pulling to either side going down the road. Now, it pulls slightly to the left at highway speeds. :confused: On the work order they also rotated and balanced all 4 wheels/tires. I'm going to start with checking the tire pressures on all 4 to see if they missed one, specifically the left front. The service rep told me that the oil service interval is still 5,000, not 10,000 as listed in a sticky at the top of this page, also :confused:

    Thanks for any tips!! I'll have to look at the results of the alignment and see what changed, they listed the "before" measurements.
