Okay, it's my turn to post! :banghead:

When I have been driving at 30 mph or more (never speeding ) and I step on the brake, I hear a knocking sound in the back. Any ideas?

I know its obvious but have you checked the brakes and rotors?

Sounds like a warped rotor perhaps... Do you get any shaking in the wheel or car's body when you're stopping?

No shaking that's noticeable, but I'll check tonight. It started right after I got the front sway bar fixed.

This happened to me... it turned out to be a cracked stud. Might be worth a second to check.
