Still working on the purchase of two ton with two speed axle. The dash indicator shows it was in low range when parked. It's a non-runner so have considered towing it home. Was wondering if the rear end could be damaged by towing it faster than it was intended to turn. Figure in low range the truck would probably only run about 20 so if I towed it faster than that speed would it hurt anything. Have about 100 miles to tow it. Is the two speed vacumn operated? Any way that I could shift it to the high side on a non runner? Thanks
