Vibration Problem

Brian Olson · 2003-03-14T22:43:19-06:00

I just bought a 1993 Bronco XLT with the 351 and E40D, truck has 110,000 miles, and has never been wrecked or lifted. Everything appears to be stock, but there is a harsh/severe vibration, clearly from the rear of the vehicle, which I have not solved with new U-Joints in the rear drive shaft. Always there under light load, but rears it's ugly head under heavy load from 45-55mph, and under constant load from 70-80mph,predominantly under load and acceleration up a hill. Already tried to shim the rear end above and beyond what looks like 7 degree factory wedges in place, to eliminate pinion angle problems, helped slightly at 20-45mph speeds , but no effect at higher speeds. Anyone with any experience with an apparently factory Bronco, please help !!!
