Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, lug wrench, jack, jack stands.
Sub-steps:
1. Check all tires for proper inflation using the tire pressure gauge. Inflate to the manufacturer's specified pressure if needed.
2. Inspect tires for uneven wear or damage. If wear is present, consider replacing the affected tires.
3. If replacing tires, loosen the lug nuts, lift the vehicle with a jack, and support it on jack stands.
4. Remove the wheels and replace with new tires. Torque lug nuts to the manufacturer's specifications (usually around 80-100 lb-ft).

3. Suspension and Drivetrain Components Inspection

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Inspect all suspension components including control arms, bushings, and struts for wear. Replace any damaged components.
2. If the driveshaft or CV joints are damaged, replace them. Remove the necessary bolts and detach the driveshaft from the differential and transmission.
3. Install the new driveshaft or CV joint and torque bolts to the manufacturer's specifications.

4. Engine and Transmission Mount Replacement

Tools Required: Socket set, jack, jack stands.
Sub-steps:
1. Inspect engine and transmission mounts for deterioration or cracking. If damaged, they need to be replaced.
2. Support the engine using a jack, then remove the bolts securing the old mounts.
3. Install new mounts and torque to the manufacturer's specifications.
