Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Inspect and Replace CV Joints

Lift the Vehicle:
- Use a jack to elevate the front of the vehicle securely.
- Place jack stands under the vehicle for safety.
Remove Wheel:
- Use a socket set to remove the lug nuts and take off the front wheel.
Inspect CV Joint:
- Check the outer and inner CV joints for cracks, tears in the boot, or grease leakage.
Replace CV Joint (if necessary):
- If damaged, remove the axle nut using a breaker bar.
- Disconnect the CV joint from the hub by removing the bolts.
- Install the new CV joint by reversing the previous steps. Ensure proper torque specifications (typically around 30-50 ft-lbs for the axle nut).

3. Inspect and Replace Wheel Bearings

Check Wheel Bearing:
- With the wheel still removed, grip the wheel hub and check for play or noise.
Remove Hub Assembly (if necessary):
- If the bearing is faulty, remove the brake caliper and rotor.
- Remove the hub assembly bolts and pull the hub away from the steering knuckle.
Install New Bearing:
- Press in the new bearing using a bearing press tool.
- Reassemble the hub assembly and torque the bolts to manufacturer specifications.

4. Check Suspension Components

Inspect Bushings and Ball Joints:
- Look for any cracks or deterioration.
Replace Worn Components:
- If any bushings or ball joints are worn, remove them and replace with new parts.
- Ensure proper alignment of components and torque to specifications.
