Hello All I own a 96 850 GLT Wagon 160,000 miles and going strong! My issue is that I have this odd vibration that comes and goes at about 70 mph. The best way to describe it is a slow pulsing vibration. It seems to be coming from the rear passenger side. I've had the tires double checked and they are perfectly balanced, my mechanic replaced the shocks as one was bad, but it still vibrates. I've had my mechanic check it over several times but he can find nothing. One clue - if the vehicle is loaded with luggage etc the vibration is barely noticeable it is much worse when the vehicle is empty. Could this be a suspension issue? Do I have a bad tire? Maybe a bad bearing? Could it be a rubber bushing is missing? Thanks in advance for your thoughts. Regards Russ
