Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat, stable surface.
Disconnect the battery to prevent electrical shorts.

2. Inspecting Suspension Components

Tools Required: Socket set, torque wrench, visual inspection tools.
Remove the wheel to access the suspension components.
Inspect struts and shocks for leaks and physical damage.
Check control arms and bushings for cracks or deterioration.
Tighten any loose bolts to manufacturer's torque specifications.

3. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, tire changing tools.
Check tire pressure and adjust to the recommended PSI.
Inspect tires for uneven wear; replace if necessary.
Ensure all tires are balanced properly.

4. Wheel Alignment

Tools Required: Wheel alignment machine (or take to a professional).
Perform a four-wheel alignment to ensure proper angles are set.
Adjust camber, caster, and toe settings as needed according to manufacturer specifications.

5. Test and Reassemble

Reinstall the wheel and tighten lug nuts to the manufacturer's recommended torque.
Reconnect the battery.
Test drive the vehicle to confirm the issue is resolved.
