This is how I check/redo my wheel alignment. This works for both front and back wheels.
First check that your frame rails are the same distance apart in front of the rear wheels and behind the front wheels and that there is no damage to the frame rails that would affect the parallism of the frame rails.
I use a laser level with a pair of C-Clamps to provide standoffs so the level clears the tire and hub-cap. I have a pair which I measured the length of the screws to be sure the stand-off distance was the same on both.
The frame measuring sticks are mounted on magnets for quick attaching to the frame. Place one in front of the back wheels (I like to place it between the mounting bolts of the crossmember just in front of the door). The second one I place between the bolts that hold the fronts clip on.
I have aluminum wheels, so I set the C-clamps to sit on the wheels as shown in the pictures. Steel wheels are generally not exactly true, so maybe a point between the mounting nuts might be better.
Project the laser towards the sticks and if the reading is the same on both sticks, then the wheel is parallel to the frame. If you are doing the back wheels, it does not matter if the mid and rear wheels have a different measurement, just as long as both measurements are the same for each wheel, then you know the wheel is parallel with the frame and pointing striaght ahead.
If I am doing the front wheels, first I do the driver\'s side wheel. I make sure the steering wheel and steering box are on-center, then I align the driver\'s wheel parallel with the frame. Then I do the passenger side. Don\'t be surprised if both sides are not exactly the same measurement. Just as long as both the front and back measurements are the same, then the wheels are parallel to the frame. Now your wheels are at 0 (zero) toe. If you want a bit of toe out, just turn the adjusting sleaves the same amount on both sides to suit.
I can check and adjust the camber with the same level and arrangement. This should be done first before setting the toe. It has a digital readout so after zeroing the readout, I place the level against the wheel vertically and take the measurement. I flip the level aound to make sure I get the same reading both ways.
