Solution

1. Preparation

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

2. Tire Inspection and Adjustment

Sub-steps:
1. Check each tire for proper inflation using a tire pressure gauge; inflate to recommended PSI if necessary.
2. Inspect tires for visible damage, uneven wear, or bulges. Replace tires if damaged.
3. Tighten all wheel lug nuts to the manufacturer’s specified torque using a torque wrench.

3. Wheel Balancing

Sub-steps:
1. Remove the front wheels from the vehicle using a socket set.
2. Mount the wheels on a wheel balancer to check for any imbalances.
3. Add wheel weights as needed to balance the wheels properly.
4. Reinstall the balanced wheels on the vehicle.

4. Suspension Inspection

Sub-steps:
1. Inspect shock absorbers and struts for leaks and physical damage.
2. Check control arms, bushings, and ball joints for wear or damage.
3. Replace any worn or damaged suspension components.

5. Alignment Check

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Ensure all alignment angles (camber, caster, toe) are set to manufacturer specifications.
3. Test drive the vehicle post-alignment to confirm the issue is resolved.
