I'm still having the vibration that every other person in here seems to have experienced with their Rover between 35 and 45 miles a hour. I have replaced my front driveshaft, changed the u-joints on it after only a year because of said vibration. I have had the tires balanced and rotated twice, ( tires are one year old as well as the rims). I have rebuilt the rear driveshaft and have had it balanced.....still have the darn vibration. I'm leaning more towards worn panhard bar bushings. I remembered experiencing "death wobble in my old 1966 Ford Bronco and replacing those bushing took care of it. Some constructive input concerning this would be much appreciated. If anyone has a different idea on the subject, I'm all ears. Btw....my Disco is a 2000 se7, 90,000 miles, 3 inch lift, steel wheels, 265-75r-16 all terrain tires.
