Sub-steps:
1. Lift the vehicle securely using jack stands.
2. Locate the transmission mounts beneath the vehicle.
3. Remove the mounting bolts using a socket set.
4. Replace the old mounts with new ones and tighten bolts to manufacturer specifications (typically about 30-40 ft-lbs).
Tools Required:
- Socket set
- Torque wrench

4. Inspect and Replace Drive Shaft/U-Joints

Sub-steps:
1. Visually inspect the drive shaft for any signs of damage or play.
