2. Rotate tires if uneven wear is detected to promote even wear across all tires.

3. Alignment Adjustment

Sub-steps:
1. Set up the vehicle on an alignment rack.
2. Measure the current alignment settings using the alignment tool.
3. Adjust the camber, caster, and toe settings as per manufacturer specifications.
  - Typical toe setting for G70: 0.1° to 0.2° toe-in.
4. Tighten all adjustment bolts to the specified torque (refer to manufacturer's specifications).

4. Suspension Component Inspection and Replacement

Sub-steps:
1. Inspect all suspension components including control arms, bushings, and shocks for wear or damage.
2. Replace any worn or damaged parts, ensuring to install them according to manufacturer specifications.
3. Torque all fasteners to specified values.
