Another note is faulty negative battery cables have been known to cause all kinds of electrical anomalies. Its a $60 part but may save you heartache in the long run if it fixes this problem or not.
Vibration
May be wheel bearings, could be a warped brake disk, unbalanced wheel, dry transfer case may need fluid, drive shaft linkage.
Vibration when diving
Your vibration can be from several different things:
Brake rotors warped, Tire out of balance, lugnuts loose, etc.
The most common reason would be a tire has thrown a weight creating the shimmy. Go to your local tire dealer (i would suggest Les Schwab) they can check it out for free, and usually balance for free too.....
Front end probably
Bent wheel, defective tyre, wheels out of balance, alignment and uneven tyre wear, defective or worn shock absorbers, excessive wear or lash in the steering/suspension components, binding front brake(s), front brake discs warped or excessive axial runout...
Most commonly it is wheel imbalance that is the culprit.
What the best grade gas to used
Premium or super....the higher the octane level the hotter, cleaner it will burn, which in turn gives you netter gas mileage.
Back wheels will not turn on 2007 yukon truck will not move
One thing that can happen is the brake pads can get rusted to the rotors or the parking brake cables can rust internally. Neither is unusual, they just need to be freed up. Jack the rear wheels up to see if they will turn. Be sure to use jack stands for safety. When you turn the wheel, you should be able to see the driveshaft turn. A guy on Community Car Talk said, " I tried putting it in neutral, spinning the good wheel really fast by hand, and then running to the cab and slamming on the parking brake. Lo and behold! That freed it"
