Solution

1. Preparation

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

2. Tire Balance Adjustment

Tools Required: Wheel balancer, socket set
Remove the wheel that exhibits shaking.
Mount the wheel on the balancer and spin it to find any imbalances.
Add weights as needed to balance the wheel and retest.

3. Tire Pressure Check

Tools Required: Tire pressure gauge
Remove valve caps from all tires.
Measure and adjust tire pressure to the manufacturer's specifications (usually found on the driver's side door jamb).
Replace valve caps securely after adjustment.

4. Suspension Inspection

Tools Required: Jack, jack stands, socket set
Use a jack to lift the vehicle and secure it with jack stands.
Inspect the shocks and struts for signs of leakage or physical damage.
Check all bushings for cracks or wear, replacing as necessary.

5. Wheel Alignment

Tools Required: Alignment tool, torque wrench
If tire wear is uneven, perform a wheel alignment.
Follow the vehicle’s service manual for alignment specifications.
Adjust toe, camber, and caster angles as necessary, tightening bolts to the specified torque.

6. Brake Component Inspection

Tools Required: Socket set, caliper tool
Remove the wheel and inspect the brake rotor for warping or uneven wear.
If warped, replace the rotor and pads as needed, following the vehicle's service manual.
Reassemble the wheel and lower the vehicle.
