Solution

1. Preparation

Gather tools and necessary parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery for safety.

2. Tire Inspection and Balancing

Sub-steps:
1. Remove the wheel covers if applicable.
2. Inspect tires for uneven wear, bulges, or damage.
3. Use a tire balance machine to check and balance the tires.
4. Reinstall the wheels and torque the lug nuts to the manufacturer's specification (typically around 80-100 ft-lbs).

3. Drivetrain Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Inspect the driveshaft for any signs of damage or excessive play.
3. Check the CV joints for torn boots or grease leakage.
4. Replace any damaged components or worn parts.

4. Engine and Transmission Mounts Replacement

Sub-steps:
1. Identify and locate the engine and transmission mounts.
2. Use a socket set to remove the bolts securing the mounts.
3. Carefully lift the engine/transmission assembly with a hoist or jack to relieve pressure on the mounts.
4. Replace the mounts with new ones, ensuring proper alignment.
5. Torque the mounting bolts to the manufacturer’s specifications.

5. Suspension Component Check

Sub-steps:
1. Inspect control arms, bushings, and struts for wear or damage.
2. Replace any worn suspension parts as necessary.
3. After replacement, perform a wheel alignment.
