Frt/Rear Diff gear ratios

[EH Jeff]

Puzzling question! 2022 Ops manual states that the Frt/Rear diff ratios are 5.38:1, but service manual states they are 3.73:1. Which one is correct? I'm gonna check my MUTT tomorrow when I get to work. I'll let you all know what I find.

18 and 19s were 3.73. 20s to current are 5.38s

Do you know anyone wanting 5.38’s ? I’ll trade my 5.38’s for 3.73’s. Or buy someone’s 3.73’s & sell these 5.38’s in my 2022.

I checked my diffs, and the I.D. Tags verify that they are 5.38's. At the same time, I figured I'd check the diff fluid levels. Both were approx 8oz low. So I checked the trans and transfer case. They too were 8oz low each. Just a FYI.

All new Rox owners don't trust whatever fluid is in your unit. Question the levels right away.
