Question about 1999 GMC Sierra
Truck goes into 4WD and the shift motors work, but when i was stuck on ice, the only thing spinning was my rear tires.
Most of the engine power is designed to go to, the back wheels UNLESS the transfer case is in LOCK position in 4 hi or 4 low..also was the front hubs locked in...some models still use lockouts in front..remember this also.. if most of the weight is up front as it is on pickups, the rear wheels are the least resistance for the power so they will move first unless thers enough weight on top of them say sandbags or firewood or just dead weight...(if the truck is used look under the vehicle to see if the front driveshaft was taken out..some folks do this for fuel economy purposes) good luck repost findings please...thnx
