Shakes or Wobbles problem
1999 GMC Yukon V8 Four Wheel Drive Automatic 186000 miles
----------------------------------------------------------------
Vehicle rides smooth until about 60 miles an hour. Vibration in front gets worse the faster you go. Two wheel drive light is on. When we checked the front drive shaft turns eventhough the 2 wheel high light is on. This vehicle has an electonic 4 wheel automatic switch.
What is cause this vibration. Are my electronic hubs bad?
