Default can you run 2 different axle ratios?

I friend has a 03 f-250 and he insists that it has different axle ratios front and rear (3.73 back and 3.90 front) so does that mean that the tranfer case is putting out different ratios or am i missing something here? I have never heard of this when running the same size tires.

thanks all

I've heard of slight diferences.. but not that much of a difference... by slight I mean 3.55, 3.54...

[img]images/graemlins/tongue.gif[/img] Actually, under certain conditions it WOULD BE POSSIBLE, and those conditions are that you have a center differential......a splitter that sends different shaft RPM to each axle as needed. My '97 ZJ with the Model 242 transfer case is set up that way and would tolerate that, but of course the useful life of that center differential would be reduced. Our '79 CJ with the Quadra-Trac has a center differential as well, and we have modified it to be more like the 242 for snow driving. [img]images/graemlins/cool.gif[/img][img]images/graemlins/AR15firing.gif[/img] When I was a kid we had several WWII army trucks that we used on our ranch to feed cows and haul fertilizer and so forth and I know for a fact that the front axle ratio was slightly higher....in other words the axle went faster PER TURN OF THE DRIVELINE than did the rear axles. That was supposed to "lead" the truck better in deep mud. These were six-by-sixes of course and they would want to crab sideways real bad if the front axle wasn't "leading" just a tad. [img]images/graemlins/crazy.gif[/img] Now.....those trucks could not run even TEN FEET on dry ground if the front axle was still engaged.....it would produce a gear bind that would soon cough up a front driveline if you didn't grab that floor lever and back up a bit and unwind the bind so you could pop it out of front axle drive.

I have always heard of a 10% or less difference. For a strictly mud truck, I guess it would work. I can attest to the fact that different ratios will work off road, but as soon as you turn onto pavement, something has to give.

The only other situation that I could think of would be if the rear tires were a different size than the front....and it would have to be quite a bit.

I guarantee it did not come from the factory with those mixed ratios.

Yeah, that's too much of a ratio to be from the factory. I've heard of guys that run mud bogs running different ratios. I bet he's pulling your leg or some one messed with his diffs.
