1. Preparation

Ensure the vehicle is on a level surface and securely lifted using jack stands.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, catch pan
Remove the transmission fluid drain plug and allow the fluid to fully drain into the catch pan.
Replace with fresh transmission fluid as specified by the manufacturer (check owner's manual for type and capacity).
Reinstall the drain plug and torque it to manufacturer specifications.

3. Check and Replace Motor/Transmission Mounts

Tools Required: Socket set, torque wrench
Remove the bolts securing the motor and transmission mounts using a socket set.
Inspect the mounts for cracks, tears, or excessive wear.
If damaged, replace with new mounts, ensuring proper alignment.
Torque the bolts to specifications.

4. Inspect and Replace CV Joints or Driveshaft

Tools Required: Socket set, pry bar
Remove the wheels for easier access to the CV joints if applicable.
Inspect the CV joints for any signs of damage or excessive play.
If damaged, remove the axle assembly using a socket set and replace with a new one.
Reassemble and torque all fasteners to specification.
