Tracking & Offset
The purpose of a Tracking is to adjust the rear axles until they are aligned with the
vehicle chassis. These procedures can be used on a trailer as well by using our King Pin
Target kit.
The following should be completed before making any measurements or adjustments:
1)
Equipment should be checked for calibration.
2)
The full weight of the vehicle must be on its wheels.
3)
The suspension must be inspected.
4)
Rear wheel clamps must be installed.
5)
Run out must be completed on the rear wheel clamps.
Tracking Procedure:
NOTE: Use the procedure of the TWO WHEEL CENTERLINE
ALIGNMENT section and complete the additional procedures to complete
Tracking.
1)
Place the TLT-28 wheel clamps on the rear tire and complete the run out
procedure.
2)
Place the TLT-36 and TLT-37 Laser guns on the rear of the vehicle with the
lasers facing to the front.
3)
Adjust the TLT-36 and TLT-37 for total rear wheel toe.
4)
Place the Wheel Centering Targets next to the front tires with the flag numbers
face to the rear.
5)
Look at the Wheel Centering Targets. Adjust axle until the lasers hit the opposite
numbers on the Wheel Centering Targets. (Refer to figure 23)
Note:
After making the axle adjustments, your objective is to have the cross-toe laser in the
hole and have the lasers hit matching numbers on the Wheel Centering Targets, i.e., if
the laser hits at 3 on the left scale, it should hit a 3 on the right scale.
