1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Balancing

Sub-steps:
1. Remove the wheel covers or hubcaps if applicable.
2. Inspect tires for uneven wear and damage, such as bulges or cracks.
3. Check tire pressure using a tire gauge and inflate to the manufacturer's specifications.
4. If tires are damaged or excessively worn, replace them.
5. Take the vehicle to a shop for professional balancing if necessary.

3. Driveshaft and Axle Check

Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Visually inspect the driveshaft and axles for any signs of damage or wear.
3. Use a torque wrench to check the torque specs on the axle bolts, re-torquing if necessary.
4. Replace any damaged components as needed.

4. Engine and Transmission Mount Replacement

Sub-steps:
1. Remove any components obstructing access to the engine mounts.
2. Use a socket set to remove the bolts securing the engine and transmission mounts.
