There was absolutely no warning. I was driving down a smooth road at about 50 mph, suddenly it felt as if I were driving over dimpled pavement, I slowed down and the vibrations continued. I pulled over to the side of the road to see if I had a flat or if the lug nuts were loose. I was only three miles from home and put on the flashers and limped back at 25 mph. Half of the time during the three mile ride the vibration went away.

My X5 is now sitting in the driveway till I have time to get it to the local mechanic. I used to do all my own work on cars but now I don't have the time. It's too bad because I actually enjoy diagnosing problems and fixing them but these days I run a company and work seven days a week. This fix would probably take me two days to repair on my own and the lost business would cost me a lot more than just letting the mechanic do his job.

Nonetheless I always like to know what caused the problem and what is needed to fix it so that the shop does not take me to the cleaners.
