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 to prevent any electrical issues.

2. Inspect and Replace Wheel Bearings

Tools Required: Socket set, torque wrench, wheel bearing puller, hammer.
Remove the left front wheel by loosening the lug nuts and lifting the vehicle with a jack.
Inspect the wheel bearing for play by shaking the wheel. If there is movement, the bearing needs replacement.
To replace, remove the brake caliper and rotor, then use a wheel bearing puller to remove the old bearing.
Install the new wheel bearing and reassemble the components, ensuring all fasteners are torqued to manufacturer specifications.

3. Check and Replace CV Joint (if necessary)

Tools Required: Socket set, CV joint puller.
If the CV joint is damaged, remove the axle from the transmission side using a CV joint puller.
Replace the CV joint assembly with a new one, ensuring proper alignment and securing the fasteners to the specified torque.

4. Inspect and Replace Suspension Components

Tools Required: Suspension tool kit, torque wrench.
Check all suspension components for wear, particularly the control arms and bushings. Replace any damaged parts.
Reassemble the suspension, ensuring all bolts are tightened to the manufacturer’s torque specifications.

5. Reassemble and Test

Reinstall the wheel and lower the vehicle to the ground.
Reconnect the battery terminal.
Perform a test drive to confirm the grinding noise has been resolved.
