Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Raise the vehicle using a jack and support it with jack stands.

2. Tire Rotation

Sub-steps:
1. Remove all four tires using a lug wrench.
2. Rotate tires according to manufacturer guidelines (e.g., front to back, side-to-side).
3. Inspect the sidewalls for any damage or bulges.
4. Reinstall the tires, tightening the lug nuts to the specified torque (usually around 80-100 ft-lbs).

3. Wheel Alignment

Sub-steps:
1. Use a wheel alignment tool to assess the current alignment settings.
2. Adjust the camber, caster, and toe angles to meet manufacturer specifications.
3. Test drive the vehicle and re-check alignment settings to ensure stability.

4. Suspension Component Replacement (if necessary)

Sub-steps:
1. Identify any worn suspension components that need replacement (e.g., bushings, struts).
2. Remove the damaged parts using appropriate tools (e.g., socket set).
3. Install new components, ensuring they are torqued to manufacturer specifications.
4. Reassemble and ensure all connections are secure.
