Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal if working on electronic components.

2. Tire Inspection and Replacement

Inspect Tires:
- Remove the tires and inspect for damage or uneven wear.
- Replace any tires that are worn beyond the tread wear indicators.
Balance Tires:
- Mount tires on a wheel balancing machine and adjust weights as necessary.
- Ensure that all tires are balanced to the manufacturer's specifications.

3. Wheel Alignment

Alignment Procedure:
- Position the vehicle on an alignment rack.
- Follow the manufacturer's specifications to adjust camber, caster, and toe settings.
- Tighten all bolts to the specified torque settings (usually around 95 Nm for control arm bolts).

4. Suspension Inspection and Repair
