After yanking out of fuel parts we found that the passenger side drive shaft closer to the transmission had a really sloppy joint. We could literally move the joint back and forth with ease between a 3/8 & a quarter inch. New drive shaft in place and the car is driving like new again with no thought noises no vibration or no rattling.
