Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace U-Joints

Sub-steps:
1. Lift the vehicle securely using jack stands.
2. Remove the driveshaft by unbolting it from the differential and transmission.
3. Inspect U-joints for play or damage; replace if necessary.
4. Install the new U-joints and reattach the driveshaft, ensuring all bolts are torqued to manufacturer specifications.

3. Check and Replace Engine or Transmission Mounts

Sub-steps:
1. Visually inspect engine and transmission mounts for cracks or deterioration.
2. If damaged, remove the bolts securing the mounts.
3. Replace the mounts with new ones, following the manufacturer’s torque specifications.
4. Recheck alignment and tighten all bolts securely.

4. Differential Inspection

Sub-steps:
1. Inspect the differential for fluid leaks and proper fluid level.
