Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, multimeter, and safety glasses.

2. Inspect and Replace Power Steering Fluid

Remove the power steering reservoir cap.
Check the fluid level; if low, add the recommended fluid type (BMW CHF 11S).
If the fluid is dark or contaminated, perform a fluid flush and replace with fresh fluid.

3. Inspect and Replace Damaged CV Joints

Raise the vehicle and remove the front wheels.
Inspect the CV boots for tears or cracks; replace if necessary.
If CV joints are damaged, remove the axle nut using a socket set.
Use a pry bar to disconnect the axle from the hub and replace with a new axle or joint assembly.

4. Check and Replace Wheel Bearings

Remove the wheel hub assembly.
Inspect the wheel bearings for excessive play or roughness.
If damaged, press out the old bearings and press in new ones using a bearing press.

5. Brake Component Inspection

Inspect brake pads and rotors for wear or debris.
Clean the brake components with brake cleaner and reseat any misaligned parts.
Replace any worn brake components as necessary.

6. Reassemble and Test

Reinstall the wheel hub and tighten the axle nut to manufacturer specifications (typically 250 Nm).
Reinstall the wheels and lower the vehicle.
Conduct a test drive to ensure the grinding noise is resolved.
