Hey everyone, This is my first LR, 00 discovery series II. I bought it used with 113000 miles on it three weeks ago. Yesterday I noticed a almost low humming noise and some vibration at slower speeds. Today driving home from work on the high way it appeared to be worse. a lot louder more vibration, if i drove around 50-60 this went away but faster or slower then that it came back (coming off the off ramp and driving in my neighborhood). It also is vibrating terribly now, to the point where it is having trouble accelerating. Up to this point it has driven incredibly smooth and very nice. I also have been super easy on her as far as driving. I've been using google-fu now for about two hours but cant seem to find any solid leads. A friend who is more mechanically minded suggested drive shaft? Anyways thank you all for any help you can provide.
