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.

Advance Adapters for SYE or even Tera Flex. Lotta folks go with Tom Woods drive shafts.
You gotta decide on the style locker you want.
