- b. Locate the engine and transmission mounts.
- c. Inspect for any cracks or excessive wear.
- d. If damaged, remove the bolts securing the mount, replace with new mounts, and torque to manufacturer's specifications.

3. Inspect Driveshaft and CV Joints

Tools Required: Socket set, jack and jack stands.
- a. Raise the vehicle and secure with jack stands.
- b. Visually inspect the driveshaft for any bends or damage.
- c. Check the CV joints for torn boots or excessive play.
- d. If damaged, replace the driveshaft or CV joints as necessary.

4. Change Transmission Fluid

Tools Required: Transmission fluid pump, socket set, drain pan.
- a. Place a drain pan under the transmission pan.
- b. Remove the transmission pan bolts and allow fluid to drain completely.
- c. Replace the transmission filter if applicable.
