Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent any electrical issues during inspection.

2. Inspect and Replace Engine/Transmission Mounts

Tools Required: Socket set, torque wrench, pry bar
Remove any components obstructing access to the mounts.
Use a pry bar to gently lift the engine and inspect the mounts for cracks or separation.
If damaged, unbolt the old mounts and replace them with new ones, tightening to the manufacturer’s torque specifications.

3. Fluid Change

Tools Required: Fluid pump, drain pan, funnel, replacement fluids
Drain the engine oil and replace with manufacturer-specified oil.
For the transmission, drain the fluid and replace it following the manufacturer's fluid type and capacity.
Recheck fluid levels post-replacement and ensure there are no leaks.

4. Inspect Driveshaft and Axles

Tools Required: Jack and jack stands, socket set
Safely lift the vehicle and remove the wheels for better access.
Inspect the driveshaft and axles for any visible damage or signs of imbalance.
Replace any damaged components.

5. Replace Spark Plugs

Tools Required: Spark plug socket, torque wrench
Remove the ignition coils or covers to access the spark plugs.
Replace old spark plugs with new ones, ensuring they are gapped correctly to manufacturer specifications.
Reassemble any removed components.
