Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a level surface and secure with wheel chocks.
Disconnect the negative terminal of the battery to prevent electrical issues during repairs.

2. Tire Rotation and Replacement (if necessary)

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheels by loosening and removing the lug nuts with a socket set.
3. Inspect each tire for damage and replace any that are excessively worn or damaged.
4. Rotate tires to ensure even wear, following the manufacturer's recommended pattern.
5. Reinstall the wheels and hand-tighten the lug nuts.

3. Align the Wheels

Sub-steps:
1. Using a wheel alignment machine, measure the current alignment settings.
2. Adjust the toe, camber, and caster angles according to the manufacturer’s specifications.
3. Ensure that each wheel is aligned correctly and make adjustments as necessary.
4. Once adjustments are made, lock the adjustments in place.

4. Inspect and Replace Suspension Components (if needed)

Sub-steps:
1. If any worn or damaged suspension components are found during the visual inspection, remove them.
2. Replace any damaged components (e.g., control arms, bushings) using a socket set.
3. Reassemble the suspension components and ensure all bolts are torqued to specifications.
