If the vibration seems to occur only while accelerating, you most
likely have a bad inner CV axle joint, either left, right, or both
sides. If it occurs under any power condition above 75 mph, you may
have an out of round axle hub in front or stub hub in back. Check all
four hubs with a dial indicator for any type of runout - lateral or
radial. If one has clearly more runout than the others, ithat hub is
the most likely culprit.
