1. Raise the vehicle securely on jack stands.
2. Remove the bolts securing the engine and transmission mounts using a socket set.
3. Replace old mounts with new OEM mounts, ensuring proper alignment.
4. Torque the bolts to the manufacturer's specifications (typically 25-30 ft-lbs).
Tools Required: Socket set, torque wrench.

4. Inspect and Replace Driveshaft Components

Sub-steps:
1. Remove the driveshaft by unbolting the universal joints at both ends.
2. Inspect the driveshaft for bends or cracks; replace if necessary.
3. Replace worn universal joints with new ones, ensuring proper lubrication.
Tools Required: Socket set, universal joint tool.

5. Balance and Rotate Tires

Sub-steps:
