Solution

1. Preparation

Tools Required: Alignment tool, jack, jack stands, torque wrench, socket set.
Ensure the vehicle is parked on a level surface.
Gather all necessary equipment.

2. Adjust Camber, Caster, and Toe

Camber Adjustment:
1. Loosen the upper control arm bolts.
2. Adjust to the specified camber angle using an alignment tool.
3. Torque the bolts to manufacturer specifications (refer to service manual for specific torque values).
Caster Adjustment:
1. Locate the lower control arm adjustment bolts.
2. Adjust caster angle as needed using the alignment tool.
3. Re-torque the bolts to specifications.
Toe Adjustment:
1. Measure the distance between the front and back of the front tires using a tape measure.
2. Adjust the tie rod sleeves to achieve the proper toe angle.
3. Ensure both sides are symmetrical and re-torque the tie rod lock nuts.

3. Final Inspection

Recheck all adjustment points to ensure they are secure and within specifications.
Perform a final measurement of alignment angles to confirm corrections.
