Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Wear safety gloves and goggles.

2. Inspect and Inflate Tires

Remove the hubcaps if applicable.
Use a tire pressure gauge to check the inflation of all tires. Inflate tires to the manufacturer's recommended pressure.
Inspect tires for uneven wear and damage, replacing any that are excessively worn or damaged.

3. Wheel Balancing

Remove the wheels from the vehicle using a socket set.
Take the wheels to a tire shop for balancing or use a wheel balancer if available.
Reinstall the wheels once balanced, ensuring to torque the lug nuts to the manufacturer's specifications (typically around 80-100 ft-lbs).

4. Suspension Inspection

With the vehicle on a lift or jack stands, visually inspect the suspension components.
Check for play in the tie rods and ball joints by wiggling them by hand; replace any components that show excessive wear.
Examine control arm bushings and replace if cracked or dried out.

5. Wheel Alignment

After ensuring all components are in good condition, take the vehicle to an alignment shop.
Request a four-wheel alignment to ensure that all angles are within manufacturer specifications.
