Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Use safety glasses and gloves for protection.

2. Inspect and Replace Tires

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench.
Check tire pressure with a tire pressure gauge and inflate to manufacturer specifications.
Inspect tires for uneven wear and replace if necessary, following these sub-steps:
- Loosen the lug nuts slightly while the vehicle is on the ground.
- Use a jack to lift the vehicle and securely position jack stands.
- Remove the lug nuts completely and take off the tire.
- Install the new tire, hand-tightening the lug nuts.
- Lower the vehicle and torque the lug nuts to the manufacturer's specifications.

3. Inspect Suspension Components

Tools Required: Wrench set, socket set, flashlight.
Visually inspect suspension components for wear or damage. If any components are found defective:
- Remove the affected part (e.g., control arms, bushings) using the appropriate sockets or wrenches.
- Replace with new parts, ensuring they are properly aligned and torqued to specifications.

4. Check and Replace Engine and Transmission Mounts

Tools Required: Socket set, torque wrench, pry bar.
Inspect engine and transmission mounts for cracks or excessive wear.
If damaged, proceed with replacement:
- Remove any components obstructing access to the mounts.
- Use a pry bar to relieve tension on the mounts.
- Remove the bolts securing the mounts to the engine and chassis.
- Install new mounts, torquing to manufacturer specifications.
