Solution

1. Preparation

Gather tools and parts required.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Power Steering Fluid

Tools Required: Funnel, fluid container
Check the power steering fluid reservoir. If low, top off with the manufacturer-recommended fluid.
If the fluid is dirty or has a burnt smell, perform a fluid flush and replace with new fluid.

3. Inspect CV Joints and Replace if Necessary

Tools Required: Jack, jack stands, socket set
Lift the front of the vehicle and secure with jack stands.
Remove the wheel to access the CV joint.
Inspect the CV boot for tears or leaks. If damaged, replace the CV joint.
- Remove the axle nut and disconnect the joint from the hub.
- Install the new CV joint, ensuring proper alignment and torque the axle nut to the manufacturer's specifications.

4. Inspect and Replace Wheel Bearings if Necessary

Tools Required: Bearing puller, socket set
With the wheel removed, check the wheel bearing for play by wiggling the wheel.
If there is excessive play or noise, remove the bearing using a bearing puller.
Install the new wheel bearing and ensure it's properly seated and lubricated.

5. Reassemble and Test

Reattach the wheel and lower the vehicle.
Reconnect the negative battery terminal.
Test drive the vehicle to ensure the grinding noise has been resolved.
