I had bad control arm bushings and the symthoms were very differant. I would get a rythmic bad vibration from the bad side that would yank the steering wheel like the tire had a flat spot in it...but it would only happen during normal accelerations and usually stopped past 40-45mph. There is a tread on here somewhere about it.

Back to somewhat on topic, a somewhat common cause of clunking during acceleration/ braking is the tramsmission mount bolts loosening/ falling out. Myself included, several on here have had this happen.

The creaking during braking I think is normal in older drivetrains. When stopping, the car is still trying to go forward while in gear and idling so suspension part will creak.
