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 during repairs.

2. Inspect Engine Mounts

Remove the engine cover (if applicable) using a socket set.
Visually inspect the engine mounts for cracks or signs of deterioration.
If damaged, replace the engine mounts:
- Support the engine with a jack and a block of wood.
- Remove the mounting bolts using a socket set.
- Install new mounts and torque to specification (consult service manual for torque values).

3. Check Transmission Fluid

Locate the transmission dipstick (if applicable) and remove it.
Wipe it clean and reinsert to check the fluid level.
If low, add the recommended transmission fluid (consult owner’s manual for specifications).
If contaminated, drain and replace the fluid:
- Remove the transmission pan using a socket set.
- Replace the filter and clean the pan.
- Reinstall the pan with new gasket and torque to specification.

4. Inspect Driveshaft and CV Joints

Lift the vehicle using a jack and secure on jack stands.
Visually inspect the driveshaft for any signs of damage.
Check CV joints for torn boots or excessive play.
Replace any damaged components:
- For CV joint replacement, remove the wheel and brake components to access the axle.
- Use a socket set to remove the axle nut and detach the axle from the hub.
- Install new CV joint and reassemble.

5. Test Ignition System

Remove spark plugs using a spark plug socket.
Inspect for wear or fouling; replace if necessary with OEM plugs.
Check ignition coils for proper resistance using a multimeter and replace if faulty.
