Disconnect the battery to ensure safety while working on electrical components.

2. Check Transmission Fluid

Remove the transmission dipstick and check fluid level.
If low, add the appropriate transmission fluid as per manufacturer specifications.
Inspect fluid condition; if dirty or burnt, consider a fluid change.

3. Inspect Driveshaft and Universal Joints

Safely raise the vehicle using jack stands.
Visually inspect the driveshaft for any signs of damage or wear.
Check universal joints for excessive play by moving them up and down or side to side.
If damaged, replace the driveshaft or universal joints as necessary.

4. Inspect Motor and Transmission Mounts

Check the condition of motor and transmission mounts for cracks or excessive wear.
If mounts are damaged, remove the old mounts using a socket set and replace them with new ones.
Torque the new mounts to the manufacturer's specified torque value.
