Measuring Front Alignment Angles
1998 Chevrolet Astro Van 2WD V6-4.3L VIN WSECTION Measuring Front Alignment Angles
Important: Set the front wheel alignment to the specifications while the vehicle is in the normally loaded condition. The vehicles that are consistently operated with the heavy loads should have toe-in adjusted with the vehicle under the heavy load. This procedure should result in longer tire life.
The satisfactory vehicle operation may occur over a wide range of front wheel alignment settings-. If the settings vary beyond specified tolerances, adjustments are necessary. Refer to WHEEL ALIGNMENT SPECIFICATIONS.
1. Measure the front alignment angles using the following steps:
1.1. Install the alignment equipment according to the manufacturer's instructions.
1.2. Measure the alignment angles. Record the readings.
1.3. Make the adjustments that are required in the following order:
^ The caster
^ The camber
^ The toe-in
2. To adjust the caster and camber, refer to FRONT CASTER AND CAMBER ADJUSTMENT (REAR WHEEL DRIVE) or FRONT CASTER AND CAMBER ADJUSTMENT (FULL-TIME FOUR-WHEEL DRIVE).
