Solution

1. Tire Inspection and Replacement

Inspect Tires: Check for uneven wear, bulges, or foreign objects.
Replace Tires: If damaged, replace with OEM or quality aftermarket tires of the same size (P195/65R15).
Tools Required: Tire iron, jack, jack stands, tire pressure gauge.

2. Wheel Balancing

Remove Wheels: Use a tire iron to loosen and remove the lug nuts; remove the wheel from the hub.
Balance Wheels: Mount wheels on a wheel balancer and add weights as necessary to achieve balance.
Reinstall Wheels: Place the wheel back on the hub, hand-tighten lug nuts, then torque to the manufacturer specification (usually around 76 ft-lbs).

3. Suspension Inspection and Repair

Inspect Components: Examine tie rods, control arms, and bushings for visible wear or play.
Replace Worn Parts: If any components are found to be damaged, replace them with OEM parts.
- Tools Required: Socket set, torque wrench, pry bar.
Recheck Alignment: After replacing parts, perform a wheel alignment to ensure correct angles.
