Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Engine Mounts (if damaged)

Sub-steps:
1. Remove any components obstructing access to the engine mounts (e.g., air intake duct).
2. Use a socket set to remove the bolts securing the engine mounts to the engine and the chassis.
3. Lift the engine slightly using a jack with a wooden block to relieve pressure on the mounts.
4. Replace any damaged mounts with new ones, ensuring they are properly aligned.
5. Reinstall the bolts to the manufacturer’s specified torque values.

3. Check and Replace Transmission Fluid (if contaminated)

Sub-steps:
1. Locate the transmission dipstick or drain plug.
2. If applicable, drain the old transmission fluid into a suitable container.
3. Replace the transmission filter if necessary.
4. Refill with the recommended type and amount of transmission fluid as per the manufacturer’s specifications.
5. Run the engine and cycle through the gears to ensure proper fluid circulation.

4. Inspect and Replace Faulty CV Joints or Driveshaft (if damaged)

Sub-steps:
1. Lift the vehicle using a jack and secure with jack stands.
2. Inspect the CV joints for any tears in the boots or play in the joint.
3. If damaged, remove the axle nut and disconnect the CV joint from the transmission.
4. Replace with new CV joints or driveshaft as necessary.
5. Reassemble and torque all nuts and bolts to the specified values.
