Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent any electrical issues.
Gather all necessary tools and parts.

2. Inspect and Replace Engine and Transmission Mounts

Sub-steps:
1. Remove any components obstructing access to the engine and transmission mounts (e.g., air intake duct).
2. Locate the engine and transmission mounts.
3. Using a socket set, unbolt the engine and transmission mounts.
4. Replace with new mounts, ensuring they are aligned properly.
5. Torque the bolts to the manufacturer's specifications (typically around 50-60 ft-lbs).

3. Inspect and Repair Drive Shafts

Sub-steps:
1. Lift the vehicle securely using a jack and jack stands.
2. Inspect the drive shafts for bent or damaged areas.
3. Check U-joints for play; replace if necessary.
4. If damage is found, remove the drive shaft by unbolting it from the differential and transmission.
5. Replace with a new or rebuilt drive shaft and torque the bolts to the specified value.

4. Check and Adjust Differential

Sub-steps:
1. Inspect the differential for fluid levels and any leaks.
2. If low, refill with the correct fluid type (typically 75W-90 gear oil).
3. Check for any signs of wear on the differential gears; replace if needed.
4. Ensure that the differential is properly aligned with the drive shafts.
