Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety goggles and gloves for protection.

2. Tire Rotation

Sub-steps:
1. Loosen the lug nuts on the front tires slightly (do not remove).
2. Raise the front of the vehicle using a jack and secure it with jack stands.
3. Remove the front tires and inspect them for damage or foreign objects.
4. Rotate tires (if uneven wear is present, consider swapping sides) to promote even wear patterns.
5. Reinstall the front tires and hand-tighten the lug nuts.

3. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Perform a four-wheel alignment to ensure all angles are set to manufacturer specifications.
3. Adjust camber, caster, and toe angles as necessary.
4. Test drive after alignment to confirm improvement in driving characteristics.

4. Suspension Component Inspection

Sub-steps:
1. Inspect components such as control arms, ball joints, and tie rods for play or damage.
2. Replace any worn or damaged components to restore proper alignment.
3. Recheck the alignment after part replacement.

Tools Required:

Jack and jack stands
Lug wrench
Torque wrench
Wheel alignment machine (for professional use)
Inspection tools (e.g., pry bar, socket set)

Parts Required:

New tires (if existing tires are excessively worn)
Suspension components (if damaged, e.g., control arms, ball joints)

Estimated Repair Time: 2-4 hours

Safety Warnings:

Ensure the vehicle is on a stable surface before lifting.
Always use jack stands when working under a vehicle.
