Solution

1. Tire Inspection and Replacement

Sub-steps:
- Raise the vehicle using a jack and secure it with jack stands.
- Remove the wheel and inspect the tire tread for uneven wear or damage.
- If tires are worn unevenly, replace all four tires to ensure balanced handling.
- Rotate the tires if they show uneven wear but are not excessively worn.

2. Wheel Bearing Inspection and Replacement

Sub-steps:
- Spin the wheel while it is still off the ground to listen for grinding noises.
- If noise is detected, remove the brake caliper and rotor to access the wheel bearing.
- Replace the wheel bearing using a bearing puller and install a new bearing with proper grease.
- Reassemble the brake components and wheel.

3. Driveshaft Inspection and Repair

Sub-steps:
- Inspect the driveshaft for any visible damage or imbalance.
- If damaged, remove the driveshaft by unbolting the universal joints and any supporting brackets.
- Replace the driveshaft with a new unit, ensuring all bolts are torqued to the manufacturer’s specifications.

4. Engine and Transmission Mount Replacement

Sub-steps:
- Visually inspect the engine and transmission mounts for cracks or separation.
- If mounts are damaged, support the engine/transmission with a jack.
- Remove the bolts securing the mounts, then replace with new mounts.
- Torque the new mounts to the manufacturer’s specifications.
