Solution

1. Preparation

Gather tools and parts required for alignment or tire replacement.
Park the vehicle on a level surface and engage the parking brake.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure of each tire.
Inflate or deflate tires to reach the recommended pressure specified in the owner’s manual.

3. Tire Rotation or Replacement

If uneven wear is detected, rotate tires to promote even wear or replace worn tires.
To rotate, loosen lug nuts, raise the vehicle with a jack, and swap front tires with rear tires. Tighten lug nuts to manufacturer’s specifications.

4. Wheel Alignment

Use an alignment machine to adjust the camber, caster, and toe settings to manufacturer specifications.
Adjust tie rod ends as necessary to align the front wheels.
Recheck alignment after adjustments.

5. Suspension Component Repair

Replace any worn or damaged suspension components identified during the inspection (e.g., bushings, control arms, tie rods).
Follow manufacturer specifications for torque values when installing new components.
