Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, jack and jack stands, torque wrench, multimeter, fluid catch pan.
Disconnect the negative battery terminal to avoid electrical shorts during repairs.
Ensure the vehicle is on a level surface and securely lifted if necessary.

2. Address Engine Mounts

Sub-steps:
1. Remove any components obstructing access to the engine mounts (e.g., air intake duct).
2. Inspect engine mounts for cracks, tears, or excessive wear.
3. If damaged, use a socket set to unbolt the engine mount from the engine block and frame.
4. Replace with a new engine mount, ensuring proper alignment.
5. Torque bolts to manufacturer specifications (refer to service manual for specific values).

3. Check Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Wipe the dipstick with a clean cloth and check fluid level and condition (should be red and clear).
3. If low, add the correct type of transmission fluid (refer to owner’s manual).
4. If discolored or burnt, drain and replace the transmission fluid.
5. Recheck the fluid level after adding new fluid.

4. Inspect and Repair Driveshaft/CV Joints

Sub-steps:
1. Lift the vehicle and secure it with jack stands.
2. Inspect the driveshaft for any visible cracks or bends.
3. Check CV joints for torn boots or grease leakage.
4. If any components are damaged, remove the driveshaft by unbolting it from the differential and transmission.
5. Replace damaged driveshaft or CV joints as necessary.
6. Reinstall and torque all bolts to the specified values.
