Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on electronic components (optional).

2. Tire Pressure Adjustment

Use a tire pressure gauge to measure the tire pressure.
Inflate or deflate the tires to match the recommended pressure found on the driver's door jamb sticker.

3. Wheel Alignment

Tools Required: Wheel alignment machine
Place the vehicle on the alignment rack.
Adjust the camber, caster, and toe angles to match factory specifications.
Lock the settings in place and document the new alignment values.

4. Suspension Inspection and Repair

Tools Required: Socket set, torque wrench, suspension tool kit
Inspect each suspension component for wear.
- Replace any worn or damaged components (e.g., bushings, control arms).
- Tighten all suspension bolts to the specified torque values.

5. Tire Replacement or Rotation

If tire wear is excessive, replace the affected tires with new ones.
If wear is uneven but within acceptable limits, rotate the tires to promote even wear.
Ensure the replacement tires are of the same specifications as recommended by the manufacturer.
