Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative terminal of the battery to ensure safety.

2. Tire Inspection and Replacement

Remove the wheels using a socket set.
Inspect each tire for uneven wear or damage. Replace any tires that are worn beyond the manufacturer's specifications.
If replacement is necessary, mount new tires according to specifications.
- Tools Required: Tire iron, jack, torque wrench
- Note: Torque the wheel bolts to the manufacturer's specifications (usually around 100-120 ft-lbs).

3. Wheel Balancing

Take the wheels to a professional tire shop for balancing or use a DIY wheel balancer.
Adjust weights on the wheel rim as necessary to achieve balance.
Reinstall the balanced wheels on the vehicle.

4. Suspension and Alignment Repair

Inspect the suspension components for any visible damage or excessive play.
Replace any worn components such as tie rods, control arms, or bushings using appropriate tools.
- Tools Required: Socket set, wrenches, possibly a ball joint separator
After replacing parts, perform a four-wheel alignment using an alignment machine to ensure all angles are within specifications.
