Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, pry bar, jack stands.
Steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the engine mounts (usually found on either side of the engine).
3. Use a socket set to remove the bolts securing the mounts to the engine and chassis.
4. Replace the old mounts with new ones, ensuring proper alignment.
5. Torque the bolts to the manufacturer's specifications (check service manual for specific torque values).

3. Inspect Driveshaft and CV Joints

Tools Required: Socket set, pry bar, and a torque wrench.
Steps:
1. Visually inspect the driveshaft and CV joints for any signs of wear or damage.
2. If any defects are found, remove the driveshaft by loosening the bolts and separating it from the transmission and rear differential.
3. Replace any damaged CV joints or the entire driveshaft if necessary.
4. Reinstall the driveshaft, ensuring all bolts are torqued to specification.

4. Replace Spark Plugs and Check Ignition Coils

Tools Required: Socket set, spark plug socket, torque wrench.
Steps:
1. Remove the engine cover if applicable.
2. Use a spark plug socket to carefully remove each spark plug.
3. Inspect the old spark plugs for signs of wear or fouling.
4. Install new spark plugs, ensuring they are gapped correctly (refer to specifications).
5. Reinstall any ignition coils, ensuring they are seated properly.
