Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if working on components that require electrical disconnection.

2. Tire Inspection and Maintenance

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench
Check tire pressure using the tire pressure gauge and inflate to the recommended PSI if necessary.
Inspect tires for uneven wear, bulges, or foreign objects. Replace tires if they are damaged or excessively worn.

3. Wheel Balancing

Tools Required: Wheel balancer
Remove the wheels using the lug wrench.
Take the wheels to a tire shop for balancing.
Reinstall the wheels once balanced, ensuring lug nuts are torqued to manufacturer's specifications.

4. Wheel Alignment

Tools Required: Alignment machine (performed at a service shop)
After balancing, check alignment using an alignment machine.
Adjust alignment as necessary to manufacturer specifications.

5. Suspension Inspection

Tools Required: Jack, jack stands, socket set
Lift the vehicle and secure it on jack stands.
Visually inspect suspension components (struts, shocks, control arms) for signs of wear or damage.
Replace any worn components as necessary.

6. Drivetrain Inspection

Tools Required: Socket set, pry bar
Inspect CV joints for torn boots or play.
Check the driveshaft for any visible damage.
Replace any damaged parts as necessary to ensure a smooth operation.
