Sub-steps:
1. Locate the transmission mounts (typically found near the transmission case).
2. Using a socket set, remove the bolts securing the mounts.
3. Replace with new mounts if cracked or excessively worn.
4. Torque the new bolts to the manufacturer’s specifications.

4. Inspect Driveshaft and U-Joints

Sub-steps:
1. Examine the driveshaft for any signs of damage or excessive play.
2. Check the U-joints for wear; if loose, replace them.
3. Reinstall the driveshaft ensuring it is properly aligned and secured.

5. Inspect Engine Mounts

Sub-steps:
