Solution

1. Preparation

Gather tools and safety gear.
Inflate tires to the recommended pressure.
Ensure the vehicle is on a flat surface and safely secure it with wheel chocks.

2. Tire Rotation

Sub-steps:
1. Loosen lug nuts on all wheels using a lug wrench.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the wheels and swap them according to the recommended tire rotation pattern (e.g., front to back, side to side).
4. Reinstall the lug nuts and tighten them to the manufacturer's specifications (typically 80-100 ft-lbs).

3. Alignment Adjustment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Ensure they perform a four-wheel alignment, adjusting camber, caster, and toe settings as necessary.
3. Verify that the alignment settings are within the manufacturer’s specifications.

4. Suspension Inspection and Repair

Sub-steps:
1. Inspect all suspension components for wear, including bushings, ball joints, and tie rods.
2. Replace any worn or damaged components using appropriate tools (e.g., socket set, wrenches).
3. Recheck alignment after replacing suspension parts.
