Important
When performing adjustments to vehicles requiring a 4-wheel alignment, set the rear wheel alignment angles first in order to obtain proper
front wheel alignment angles.
Perform the following steps in order to measure the front and rear alignment angles:
1. Install the alignment equipment according to the manufacturer's instructions.
2. Jounce the front and the rear bumpers 3 times prior to checking the wheel alignment.
3. Measure the alignment angles and record the readings.
If necessary, adjust the wheel alignment to vehicle specification and record the before and after measurements. Refer to Wheel Alignment Specifications
in SI.
Important
Technicians must refer to SI for the correct wheel alignment specifications. SI is the only source of GM wheel alignment specifications that is
kept up-to-date throughout the year.
Test drive vehicle to ensure proper repair.
