How do I change the wheel bearings on my Audi A2?

I have noticed a low pitched humming sound coming from my car's wheels and suspect it may be due to worn wheel bearings. How can I change them without damaging my car?

Before attempting to change the wheel bearings on your Audi A2, it is important to have the proper tools and equipment. This includes a jack, lug wrench, socket set, and possibly a bearing puller.

Start by removing the wheel and brake caliper, and then use a socket to remove the hub nut. Once the hub is free, you can remove the old bearing and press in the new one.
