Solution

1. Tire Inspection and Replacement

Sub-steps:
1. Verify tire pressure using a tire gauge; adjust to manufacturer specifications if necessary.
2. Inspect tires for uneven wear; replace any tires that are excessively worn or damaged.
3. Rotate tires if needed to balance wear across all tires.

2. Wheel and Suspension Components

Sub-steps:
1. Remove the wheel using a socket set to access the brake and suspension components.
2. Inspect the wheel bearings for play or noise; replace if necessary.
3. Check suspension components (control arms, bushings, struts) for damage; replace any worn or broken parts.

3. Driveshaft and CV Joint Inspection

Sub-steps:
1. Lift the vehicle securely on jack stands and remove any protective covers if needed.
2. Inspect the driveshaft for signs of damage, such as dents or bends.
3. Check CV joints for cracks or leaks; replace any damaged CV joints.

4. Engine Mount Replacement

Sub-steps:
1. Disconnect the battery and allow the engine to cool.
2. Support the engine with a jack and remove the old engine mounts.
3. Install new engine mounts according to manufacturer specifications; torque to specified values.
