Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Tire Inspection and Rotation

Sub-steps:
1. Remove all four tires using a socket set.
2. Inspect each tire for uneven wear; replace any damaged tires.
3. Rotate tires to ensure even wear distribution.
4. Reinstall tires and torque lug nuts to manufacturer specifications (typically 80-100 lb-ft).

3. Wheel Balancing and Alignment

Sub-steps:
1. Mount the tires on a balancing machine to check for imbalances.
2. Adjust weights as necessary to achieve balance.
3. Perform a wheel alignment using an alignment machine, adjusting camber, caster, and toe as per specifications.

4. Inspect and Replace Engine/Transmission Mounts

Sub-steps:
1. Visually inspect engine and transmission mounts for cracks or deterioration.
2. If mounts are damaged, remove the bolts securing them (typically 13-18 mm).
3. Replace with new mounts and torque bolts to manufacturer specifications.

5. CV Joint and Drive Shaft Inspection

Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Inspect CV joints for tears or excessive play.
3. Replace any damaged CV joints or drive shafts.
4. Ensure all connections are secure and check for proper torque.
