Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and securely elevated with jack stands.
Disconnect the battery if working on electronic components.

2. Tire Inspection and Replacement

Check all tires for proper inflation and replace any that are damaged or excessively worn.
- Tools Required: Tire pressure gauge, jack, jack stands, tire iron.
- Sub-steps:
  1. Remove the wheel covers if applicable.
  2. Use the tire pressure gauge to check tire pressure against manufacturer specifications.
  3. Inspect tread depth with a tread depth gauge; replace tires if tread is below 2/32 inches.
  4. If a tire is damaged, use the tire iron to remove it and replace it with a new or spare tire.

3. Suspension Inspection and Repair

Inspect and replace worn suspension components as needed.
- Tools Required: Socket set, torque wrench, pry bar.
- Sub-steps:
  1. Remove the wheel for better access to suspension components.
  2. Inspect the struts and shocks for leakage and damage.
  3. Check control arms and bushings for wear; replace if cracked or degraded.
  4. If any parts are found faulty, unbolt them using the socket set and replace with new components, torquing to specifications.

4. Wheel Alignment

Perform a wheel alignment to ensure proper adjustments.
- Tools Required: Alignment machine (professional service).
- Sub-steps:
  1. Drive the vehicle onto an alignment rack.
  2. Follow the machine's instructions to adjust the camber, caster, and toe settings.
