yesterday my truck started to vibrate in the front end, sounds like its coming from the drivers side. its a 94 f150 4x4 with auto lockouts. this only happens when i let off the gas pedal and coast at speeds over 30 mph. if i put it in neutral it will do it even worse, if i press the gas it goes away. it needs lower ball joints (no surprise there lol), i just did the wheel bearings 5 months ago. what could be the cause??? possibly the cv shaft????

thanks in advance!
