Went to Circuit City last nite and ended up having to do a U-turn... wasn't going fast at all - the space I turned in was only two lanes wide, but I had to cut the wheel all the way left. Almost all the way through the turn I hear a pretty loud POP (loud enough to concern me a little) from underneath the car. Any ideas? Should I be worried? The nearest Isuzu dealership is about 45 minutes up the road... not a trip I can take on my lunch break. Sounded like it came from the center of the car -- maybe the transfer case?
