4a) For Run-Out using
Hub Adapters
1) Mount the Hub Adapters on all four wheels
2) Lift the Vehicle up on the side you are going to perform Run-Out on.
3) Hang a Laser Gun and Combi Gauge on the two wheels in the air. Level and
turn the laser Gun on.
4) With the Combi Gauge reflecting the laser beam back at the Laser Gun, rotate
the wheel until the Laser beam moves on the Laser Box Face.
5) Set the Toe Dial on the Combi Gauge to a number on the Laser Box Face.
6) Rotate the wheel until you can see a high point on the Laser Box Face.
I.E. If
you have set the Toe Dial so the laser beam is on the 3 of the Laser Box Face
and when the wheel is rotated the laser beam goes to the number 4 before
returning back to the number 3. When the laser beam is on the number 4 after
the wheel is rotated, this would be the high point of the Run-Out
7) Mark the wheel and set the vehicle down with the mark in the 12 o’clock
position. This is the Run-Out of the Wheel.
8) Repeat this procedure for the other three wheels.
Note:
For a Two-wheel Centerline alignment, run out should be adjusted on the front wheels. For a
Two-wheel Thrust Angle or a total Four-wheel alignment, adjust run out on all wheels.
5) Lower the car and jounce the car to settle the suspension. Be sure that the front turning
plates and rear slip plates are released and move freely.
6) Hang the TR-30 on the left front wheel clamp to measure camber, caster and SAI
a) For camber readings: with the tire in a straight-ahead position, note the reading of
the camber bubble on the TR-30.
b) For caster readings: swing the tire
out
20 degrees and adjust the caster bubble to
zero. Then, swing the tire
in
20 degrees and note the reading of the caster bubble.
c) SAI: lock the brakes with the brake pedal depressor, then swing left front wheel
out
20 degrees, zero the SAI scale on the top of the TR-30, and lock the gauge in place,
swing
in
20 degrees and note the reading.
d) Repeat process on the right front wheel.
Note:
Any and all adjustments to caster, camber or SAI, if required, must be made before
measuring toe.
e) To read rear wheel camber, hang the TR-30 Easy Check Angle Gauge on each of
the Rear wheels. Read Camber as described above.
7) Hang the TR-36 left laser gun and TR-37 right laser gun on the rear wheel clamps or hub
adapters so the lasers will “shoot” towards the front of the vehicle.
a) Hang the Frame Centering Flags on the vehicle at roughly the opposite corners of
the driver’s compartment. (The outside corners of the frame.)
Note:
Be sure that the Frame Centering Flags have been calibrated. Calibration of the
Frame Centering Flags is covered on page 14, in the calibration section of this manual.
