Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace Wheel Bearings

Lift the Vehicle: Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the Wheel: Use a socket set to remove the lug nuts and take off the wheel.
Check Wheel Bearing Play:
- Grasp the wheel and try to move it side to side. If there is excessive play, the bearing may need replacement.
Remove the Hub Assembly:
- Remove any retaining clips or bolts securing the hub assembly and detach it from the steering knuckle.
Replace the Bearing:
- Remove the old bearing and press in the new one using a bearing press tool.
- Reinstall the hub assembly and secure it with bolts to the specified torque value (refer to the service manual for exact specifications).
Reattach Wheel: Place the wheel back onto the hub, hand-tighten the lug nuts, and lower the vehicle. Torque the lug nuts to the manufacturer’s specifications.

3. Inspect and Replace Suspension Components

Examine Control Arms and Bushings:
- Check for any visible damage, cracks, or excessive wear on control arms and bushings.
Replace Damaged Components:
- If any components are found to be damaged, remove the affected control arm by unbolting it from the chassis and the steering knuckle.
- Install the new control arm, ensuring all bolts are torqued correctly.
Recheck Alignment:
- After replacing any suspension components, perform a wheel alignment to ensure proper handling and tire wear.
