Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Inspect and Replace Tires (if necessary)

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect tires for any bulges, cracks, or uneven wear.
3. If damaged, replace with new tires that match OEM specifications.
4. Reinstall the wheel and torque lug nuts to the manufacturer’s specifications (typically around 80-100 ft-lbs).

3. Check and Balance Wheels

Sub-steps:
1. Remove the wheels and take them to a tire shop for balancing.
2. Ensure that weights are applied correctly to achieve a balanced setup.
3. Reinstall the balanced wheels on the vehicle, following torque specifications.

4. Inspect Suspension Components

Sub-steps:
1. Use a jack to lift the vehicle and support it securely with jack stands.
2. Visually inspect all bushings, struts, and control arms for signs of wear.
3. Replace any worn components using OEM parts, following specific torque values for fasteners.

5. Check Driveshaft and Axle Components

Sub-steps:
1. Inspect driveshaft for any signs of damage or play at connections.
2. Tighten or replace any loose or damaged fasteners.
3. If necessary, replace worn CV joints or axles.

6. Inspect Engine and Transmission Mounts

Sub-steps:
1. Visually check engine and transmission mounts for cracks or deterioration.
2. If mounts are damaged, support the engine/transmission and replace with new mounts.
3. Torque new mounts to the specified manufacturer’s values.
