I know this isn't year correct, but still applys to lowered cars. My 2001 Ford Ranger was develeping a driveshaft noise on deceleration. Thought it was a U-joint. Checked under the truck & seen that the rear shackles brackets had rusted & the springs were resting on the frame. Replaced the OEM tin foil ones with some Dorman steel ones & the noise went away. Those rusted bracket changed the pinion angle enough to cause a problem. My lowered Merc has that same noise when getting off the gas. Guess I'll have to bring the plnion angle down a little.
