Solution

1. Preparation

Gather tools and equipment: jack stands, socket set, OBD-II scanner, torque wrench, and wheel chocks.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.

2. Inspect and Replace Tires

Sub-steps:
1. Remove the wheel covers or hubcaps if applicable.
2. Loosen lug nuts slightly while the vehicle is on the ground.
3. Lift the vehicle using a jack and secure it with jack stands.
4. Remove the lug nuts and take off the wheels.
5. Inspect tires for uneven wear or visible damage; replace if needed.
6. Balance the tires using a tire balancing machine.
7. Reinstall the wheels, tighten lug nuts to manufacturer specifications (typically 100-120 ft-lbs).

3. Inspect Suspension Components

Sub-steps:
1. Check all suspension components (control arms, bushings, shocks) for signs of wear or damage.
2. Replace any worn or damaged parts as necessary.
3. Reassemble any components that were removed for inspection.

4. Check and Replace Engine/Transmission Mounts

Sub-steps:
1. Inspect the engine and transmission mounts for cracks or excessive wear.
2. If mounts are damaged, use a socket set to remove the mounting bolts.
3. Replace with new mounts, ensuring proper alignment.
4. Torque the bolts to manufacturer specifications.

5. Inspect and Repair Driveshaft/CV Joints

Sub-steps:
1. Examine the driveshaft and CV joints for any signs of wear or damage.
2. If there is visible damage, remove the driveshaft by loosening the bolts connecting it to the differential and transmission.
3. Replace any damaged CV joints or driveshaft components.
4. Reinstall the driveshaft, ensuring all bolts are torqued to specifications.
