I have this wierd knocking noise when i left off the clutch when downshifting or when the clutch in let off fast?? I have talked to few people but no one with seven....anyone had a problem like this??? Im thinking its the drive shaft??

 

bushings in the rear...jack it up and move the wheels from their face foward and back see if they creak

 

i had the same sound but my shifter would go up and down checked under the car only to find out that the power plant frame bolts were loose front and back
