Solution

1. Preparation

Gather tools including a jack, jack stands, tire pressure gauge, torque wrench, and wheel balancer.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Tire Inspection and Inflation

Sub-step 1: Check tire pressure with a tire pressure gauge; adjust as necessary to match recommended PSI found on the driver’s door jamb.
Sub-step 2: Visually inspect tires for bulges, cracks, or uneven wear. Replace any damaged tires.

3. Wheel Balancing

Sub-step 1: Remove the wheel from the hub using a socket set.
Sub-step 2: Mount the wheel on a wheel balancer and spin to identify heavy spots.
Sub-step 3: Attach balancing weights to the wheel to ensure proper balance.
Sub-step 4: Reinstall the wheel and torque lug nuts to manufacturer specifications (typically around 80-90 ft-lbs).

4. Suspension Inspection

Sub-step 1: Inspect struts and shocks for leaks or damage; replace if necessary.
Sub-step 2: Check control arms and bushings for wear; replace if any play is detected.
Sub-step 3: Tighten any loose suspension components.

5. Wheel Alignment

Sub-step 1: Take the vehicle to a professional alignment shop.
Sub-step 2: Ensure that the alignment is adjusted to the manufacturer's specifications.
