TominKy said: (quoted from post at 20:40:22 12/07/09) Old: I had a 1980 suburban with 4-wheel drive that could not be driven on dry pavement, so obviously the gear ratios were different fore and aft and allowed for some slip on slick surfaces. That being said I have no idea what the ratios were front to back, but from that experience, I would say that if driven in four wheel only on slick surfaces the close ratios will be fine.

Tom you can't do this on many 4x4's. There's enough wear on tires, or even difference between tires, that you cannot and should not run conventional 4x4's on dry pavement.
My old Toy Landcruiser had identical front/ rear--4:11
Many US 4x's have slightly mismatched ratios. For example, nearly all (especially older) 4x4's used Spicer front axles and not necessarily Spicer rear. This meant that your Spicer 3:54 or 4:10 front might not match your "Corporate" 3:55 or 4:11 rear, thus you were "off" right out of the chute.
Except for "full time" 4x4's no conventional transfer case was ever meant to run on pavement, wet or dry.
I've never heard of some of the ratios being discussed here. I would suggest you recount the teeth. By the way it's REALLY inconvienent to refer to an axle by tooth count, since no one else does.

He got this wild idea that we should get a convoy of AC tractors and drive them from Charlotte, Michigan 105 miles to LaGrange, Indiana.
