Four wheel drive will not disengage on a 1999 Chevrolet Suburban if the actuator has been damaged or the circuit has a short in it. Checking the fuse and connectors can be a quick repair.
Your electrical circuit may be disconnected somewhere.
No it is too short.
i would check right rear axle if it is 4 wheel drive or all wheel drive or rear wheel drive. She may also have broken belt in tire. you may check wheel bearing or lug nuts for tightness.
if its rear wheel drive then check differential and if it is a front wheel drive car or diferential is fine then a gear in the trannsmission is sheered
AWD
Check out the link in the Reated Links section, below. It has a list of parts required.
Check the sticker under the hood near the center of the vehicle, it should show "all wheel drive" if it is all wheel drive, or look under the vehicle to see front axels and wheel drive shafts and rear drive shaft and rear end "pumpkin"
you should check with the company. then you should file a law suit if you have 2 wheel drive
ChecksIf it is a front wheel drive car, better check the wheel bearings, they sound kind of dry and you don't want them coming loose while driveing, ,,if it is a rear wheel drive, you might check the wheel bearings and check the differential and make sure it has differential oil in it
Check your u joints on the drive shaft or the transmission mount..
The short answer is - You Don't..... Seriously it will cost more to do this than it would to just buy a 2WD model.
