Axle gear ratio

[Dream Machine2001xj]

How can i tell what axles and the gear ratio and spline my jeep has i have a 2001 xj 4.0l automatic with np231 transfercase

Axle ratio unless someone has changed it is 3.55. Is there a flat spot on the bottom looking at the rear of the rear diff? Do you have ABS brakes?

If you want to, post a pic of that pumpkin and we'll have no problem telling you the axle and spline count.

I will post a pic of my axle in a lil bit it does not have abs

No abs and a 2001 automatic, safe bet you have a 29 spline Chrysler 8.25 with 3:55 gearing. Fun part will be opening it up to see if you have limited slip

Like Jim said, its an 8.25. And if its original it will be the 29 spline.
