Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect and Balance Tires

Sub-steps:
1. Remove wheel covers or hubcaps if applicable.
2. Use a tire pressure gauge to check each tire's inflation and adjust to the manufacturer’s recommended pressure.
3. Inspect tires for uneven wear; replace if necessary.
4. If tires are in good condition, use a tire balancing machine to balance each tire.

3. Check and Align Wheels

Sub-steps:
1. Use an alignment tool to check wheel alignment.
2. Adjust the alignment angles (camber, caster, toe) to meet manufacturer specifications.
3. Tighten all related hardware to the specified torque values.

4. Inspect and Replace CV Joints and Drive Shafts

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Inspect CV joints for any cracks or tears in the boot.
3. If damaged, remove the axle nut and disconnect the CV joint from the hub.
4. Replace the CV joint or drive shaft as necessary, ensuring proper installation of new parts.

5. Examine Engine and Transmission Mounts

Sub-steps:
1. Raise the vehicle and support it securely.
2. Visually inspect engine and transmission mounts for cracks or excessive wear.
3. If mounts are damaged, remove the bolts securing the mounts to the engine and frame.
4. Replace with new mounts and torque bolts to the manufacturer's specifications.
