Visual Inspection: Look for any visible damage or bends in the driveshaft.
Check U-Joints: Ensure U-joints are lubricated and free of play; replace if worn.

4. Engine and Transmission Mounts

Inspect Mounts: Check for cracks or excessive wear on the mounts.
Replace as Needed: If mounts are damaged, replace them using a socket set. Torque new mounts to manufacturer specifications.
