Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical issues during repairs.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, pry bar.
Remove the bolts securing the engine mounts using a socket set.
Use a pry bar to gently lift the engine and remove the old mounts.
Install new engine mounts, ensuring that they are seated properly.
Torque the bolts to manufacturer specifications (refer to service manual for specific values).

3. Transmission Fluid Change

Tools Required: Transmission fluid pump, fluid catch pan, socket set.
Locate the transmission pan and remove the bolts to access the fluid.
Drain the old transmission fluid into a catch pan.
Replace the transmission filter if applicable and install a new gasket.
Refill with the appropriate type of transmission fluid as specified in the owner’s manual.

4. Inspect and Replace Spark Plugs and Ignition Coils

Tools Required: Socket set, torque wrench, dielectric grease.
Remove the ignition coil cover (if applicable) to access the ignition coils.
Disconnect the electrical connectors from the coils, then remove them using a socket set.
Replace old spark plugs with new ones, applying dielectric grease to the boots.
Reinstall the ignition coils and secure them with bolts, torquing to manufacturer specifications.

5. Check and Balance Tires

Tools Required: Tire balancer, jack, lug wrench.
Remove the tires from the vehicle using a lug wrench.
Inspect the tires for uneven wear; replace if necessary.
Mount the tires on a tire balancer and adjust as needed to eliminate vibrations.
