RE: 4x4 Front Diff. ratio?
Gang,
Based on the responses I can't say I'm glad I asked this question? Seems like a no brainer??? And if the ratios front/rear are the same its because Dodge doesn't use a center differential. This is my first Dodge and many of my previous Chevy 4X4's had different gears front to back. For example one had a 3:42 rear and a 4:10 in the front. It also had a New Process 203 transfer case "center differential" that supported different gears front to rear. Having a lower gear in the front really helps when your locked in low range off road conditions. I expect the Dodge even without the center diff. will still be slightly different since your only suppose to use 4 wheel during times of poor traction. I've looked all over and can't find front axle specs. anywhere.

I know the guys are right. They have to be the same or you couldn't drive it very far without something breaking, unless of course, you staggered the tire sizes front to rear---but that is a completely different complicated subject.

1) If you owned a Chevy with 3.42's in back and 4.10's in front and a NP203, you would have burned up the differential assembly in your Xfer case extremely quickly - like, probable less than 1k miles.
2) The only reason the 203 has a "center differential" is because it is a full-time 4WD transfer case. If you drive your truck around in 4WD much, you've probably noticed that it lurches and skips, that's because in a modern part-time Xfer case, there is no center diff (it was a major weak point in the 203) and the drivelines spin at the same rate. Even with the same gears in both axles, the front tires will turn at a slightly different rate than the rears during a tight turn
3) The only place I've seen different gears used front/back is in mud/sand drag racing rigs. Sometimes they run a little taller gear in the back so the fronts will steer the rig a little better
4) Having a lower gear in front than the back does not help at all in adverse traction conditions
5) All modern trucks - including your Dodge - will have the same axle ratios in both ends
Hope that helps.

RE: 4x4 Front Diff. ratio?
I'll be speaking with the Ram dealer this week to find out for sure on the Dodge front axle and otherwise I'll see if I can come up with the old GM specs too.

Uhhhhhhh.... I think somebody may have fed you some misinformation at some point: couple things:
