I had a clunk every time I hit a bump in the rear of my 94 n/a 850, so I replaced the rear shocks with Bilstein. There was a bit of an improvement, but I still had the clunking noise. Ozark Lee had a write up about the rear delta links, so I changed them out last weekend. OH MY #$%^!@#! GOD, its like driving a new car. I can't believe the difference. It was an all day job and the methodology I ultimately used to remove them was heating them up until the rubber melted away. After that they came out no sweat. Anyways, if you have a clunk in the back every time you hit a bump, change out the rear delta links. I used aftermarket from Groton for $60.
