2. Use a socket set to unbolt the engine mount from the engine block and chassis.
3. Replace with new engine mounts; ensure proper alignment.
4. Torque bolts to the manufacturer’s specifications (consult repair manual).

3. Check and Replace Driveshaft or CV Joints

Sub-steps:
1. Raise the vehicle using jack stands and remove the front wheels.
2. Inspect the driveshaft and CV joints for signs of wear or damage.
3. If necessary, unbolt and remove the damaged driveshaft or CV joints.
4. Install the new part and torque the bolts to specifications.

4. Change Transmission Fluid

Sub-steps:
1. Drain the old transmission fluid using a fluid pump or drain pan.
2. Replace the transmission filter if applicable.
3. Refill with the recommended transmission fluid type and capacity.
4. Check fluid levels after running the engine for a few minutes and adjust as necessary.

5. Clean Throttle Body

Sub-steps:
1. Remove the air intake duct to access the throttle body.
