Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool before starting.

2. Tire Inspection and Balancing

Tools Required: Tire pressure gauge, jack, jack stands, torque wrench.
Check tire pressure and inflate to the recommended specifications.
Inspect tires for uneven wear or damage.
If necessary, remove the wheels and balance them using a tire balancing machine.
Reinstall wheels and torque lug nuts to manufacturer specifications.

3. Suspension Inspection

Tools Required: Wrench set, pry bar, jack, jack stands.
Lift the vehicle using a jack and secure it with jack stands.
Visually inspect struts, shocks, and bushings for signs of wear or damage.
Replace any compromised components as needed.

4. Engine Mount Replacement

Tools Required: Socket set, torque wrench, pry bar.
Locate the engine mounts, typically found on the sides or bottom of the engine.
Use a pry bar to support the engine and remove the bolts securing the mounts.
Replace the worn mounts with new ones and torque the bolts to manufacturer specifications.

5. Final Checks

After repairs, perform a visual inspection of all work done.
Ensure all tools are removed from the engine bay and under the vehicle.
