Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to ensure safety when working on electrical components.

2. Tire Inspection and Replacement

Remove the wheel covers or hubcaps if applicable.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.
Inspect the tire for uneven wear, bulges, or punctures.
If tires are damaged, replace them with new ones, ensuring proper tire size and type.

3. Wheel Alignment and Balancing

Take the vehicle to a professional alignment shop if misalignment is suspected.
Ensure all four wheels are balanced; this may need a tire balancing machine.
Adjust alignment angles as per manufacturer specifications.

4. Suspension Component Inspection

Visually inspect the suspension components, including control arms, struts, and bushings.
If any components show signs of excessive wear or damage, replace them as necessary.
Tighten any loose bolts or nuts to the specified torque values.

5. Driveshaft and CV Joint Inspection

Inspect the driveshaft for any visible damage or excessive play.
Check the CV joints for torn boots or grease leaks.
Replace any damaged driveshaft or CV joints.
