Re: can you run 2 different axle ratios?
[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.
