The rattling noises you are hearing when you go over bumps are most likely caused by bad strut tower insulators. These usually go bad about this time for the 1999 model. My Camry needs to have the whole tower replaced, but the first thing that went bad was the insulators, and it caused the car to rattle over bumps really bad. The steering problem you're having could possibly be the power steering pump going bad, although then again, it could be the nut that you are making reference to. I've never heard anything about that problem, although I'm sure there is a local mechanic who could be qualified to work with the steering wheel and air bag system, I'd most likely take it to a dealership somewhere to get it fixed. -- Just to be on the safe side. Although I'm not sure how much it would cost to fix, I'm sure the labor is what will cost you the most. It will probably take them at least a hour or so to get to all of that beneath the air bag assembly.
