Sub-steps:
1. Safely lift the vehicle using a jack and secure with jack stands.
2. Locate the transmission mount and remove the bolts securing it to the transmission and the frame.
3. Install the new transmission mount, aligning it properly, and torque the bolts to manufacturer specifications.
Tools Required: Socket set, torque wrench.
Safety Warnings: Ensure the vehicle is securely supported on jack stands.

4. Inspect and Replace Driveshaft or Universal Joints

Sub-steps:
1. Check the driveshaft for any visible damage or excessive play.
2. If the universal joints are worn, remove the driveshaft by loosening the bolts at the differential and transmission ends.
3. Replace any damaged universal joints and reassemble the driveshaft, ensuring all bolts are torqued to specification.
