Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat, level surface and engage the parking brake.
Safety warning: Ensure the vehicle is in gear or in 'Park' mode before lifting.

2. Tire Inspection and Replacement

Sub-steps:
1. Remove the wheel covers or hubcaps if applicable.
2. Using a jack, lift the vehicle and secure it with jack stands.
3. Inspect each tire for bulges, cuts, or uneven tread wear.
4. Replace any damaged tires with new ones. Ensure to check the size and specifications match.

3. Wheel Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a lug wrench.
2. Take the wheels to a tire shop or use a wheel balancer.
3. Balance each wheel by adding weights as necessary.
4. Reinstall the balanced wheels onto the vehicle, ensuring lug nuts are torqued to the manufacturer's specifications (typically 100-120 lb-ft).

4. Suspension Inspection and Repair

Sub-steps:
1. Inspect suspension components (control arms, bushings, and tie rods) for any play or excessive wear.
2. Replace any worn suspension parts with new OEM or high-quality aftermarket parts.
3. Reassemble any components removed for inspection.

5. Wheel Alignment

Sub-steps:
1. After replacing any necessary components, drive the vehicle to an alignment shop.
2. Ensure that the alignment is set to the manufacturer's specifications.
3. Test drive the vehicle post-alignment to confirm the issue is resolved.
