    It snowed and iced last night here in Kansas, and today I pulled my friend's Heep Wagoneer around his house so he could work on it in the garage. I put my truck into 4-Lo so I would have some power as well as traction. Well, my friend said, "Your front wheels are spinning faster than your rear wheels." This got my attention, but I didn't really worry about it. Is this normal or is something wrong? Could it be that the gear ratio in the front is different from the rear?

    Probably more likely you have an open diff front and rear, and one tire was just spinning slowly due to friction (from the other axle) Even if the gears were different, I don't think it would be physically possible to just watch and say conclusively that one was different ratio than the other.

    So, you got hit by the ice and snow storm, too, huh?!?! That makes the two of us!! We got hit so bad here, 100 miles from you, that we didnt go to work today!! Most of the town didnt anyhow. I am getting tired of this white crap on the ground. Its ok when we get a little bit, but geez, it dumps like 8 inches once a week!! This sucks!!

    It's a diff thang. An open differential will spin one wheel at twice it's normal (road) rpm if the other is stationary. When one wheel turns more (as in a curve or loosing traction) it's picking up the extra revolutions from the slower side (per drive shaft RPM X rear end gear). 'Make sense?

    Yeah makes sense, but all 4 tires were spinning though.
