1998 GMC Envoy 2WD V6-4.3L VIN WSECTION Measuring Front Alignment Angles
A wide range of front wheel alignment settings allow for satisfactory vehicle operation. You should make an adjustment if the settings vary beyond certain tolerances. Wheel alignment specifications are a guideline for vehicle diagnosis and for repairs.
Important: Set the front wheel alignment to specifications while the vehicle contains a typical load. Vehicles which are consistently operated with heavy loads should have the toe-in adjusted with the vehicle under heavy load. This procedure results in longer tire life.
1. Measure the front wheel alignment angles.
2. Install the alignment equipment according to the manufacturers instructions.
3. Measure alignment angles and record the readings. If adjustments are required, make the adjustments in the following order:
3.1. Adjust the caster.
3.2. Adjust the camber.
3.3. Adjust the toe in.
