The front bearings of a VW make up part of the wheel and brake assembly. Over time, components in these areas can become worn and damaged, requiring replacement. If you hear a grinding noise from the front of your vehicle then it is possible that you will need to replace your front wheel bearings. You can pick up replacement bearings from your local auto store.
Engage the parking brake on the VW. Raise the vehicle up off the ground using a car jack. Support the car with jack stands.
Use a wrench to loosen the lug nuts on the front wheel. Remove the nuts and carefully lift the wheel from the vehicle. Put it in a safe area for reattachment later.
Locate centre cap near the axle on the front wheel. Use a flat-headed screwdriver to carefully pry it off. Use a screwdriver to remove the cottar pin which locks the bearings in place. Pull the outer bearings from the vehicle.
Use a wrench to remove the mounting bolts on the brake assembly. Lift the brake caliper from the vehicle. Remove the safety bolts on the hub and lift it from the vehicle. If it is difficult to move, use a wooden mallet to gently knock it out of place. Lift the inner bearings from the vehicle.
If the bearings have scratches or grooves then they should be immediately discarded. Replace the bearings and reassemble the brake and wheel assembly following the removal steps in reverse. Repeat the process on the other front wheel.
