Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Tire Rotation

Step 1: Loosen lug nuts on all four tires using a lug wrench.
Step 2: Lift the vehicle using a hydraulic jack and secure it with jack stands.
Step 3: Remove tires and rotate them according to the manufacturer's recommended tire rotation pattern.
Step 4: Reinstall the tires and hand-tighten the lug nuts.

3. Wheel Alignment

Step 1: Use an alignment machine to measure the toe, camber, and caster angles.
Step 2: Adjust the alignment settings to meet manufacturer specifications.
Step 3: Tighten all bolts to specified torque values (refer to the service manual for specific torque).
Step 4: Test drive the vehicle to ensure proper alignment.

4. Suspension Inspection and Repair

Step 1: Visually inspect suspension components for wear or damage.
Step 2: Replace any worn or damaged components such as control arms or bushings.
Step 3: Reassemble the suspension and ensure all fasteners are torqued to specifications.
Step 4: Check wheel bearings; replace if any play or noise is detected.

5. Final Tire Inspection

Step 1: Inspect the tires for any additional damage or uneven wear patterns.
Step 2: If tires are excessively worn, consider replacing them.
Step 3: Ensure all four tires are balanced properly.
