Symptoms: Your car is tilting, and there is a loud thumping noise

If you're not strong enough, that's one thing, but this is something any capable human being with common sense should be able to figure out. In your trunk, you have a spare tire. Within that spare tire is usually a small car jack with a built-in lever and lug nut ratchet. Put the jack on a stable part of the frame (no plastic pieces!), pump up the car, remove the lug nuts and put the donut on. Just make sure you adequately tighten the nuts and slowly bring down the jack.
