You definately have a high pinion Dana 30 front. You will have to look at the rear to determine which it is. You can also look at the tags on the axles to see what gear ratio you have.
 
What Tranny do you have, Automatic or Manual?
 
Dana 30 High Pinion - Reverse Cut - 27 Spline, 1.16" Diameter Shafts, 7.13" Ring Gear - used '84-'99.
'95+ have 5-297x U-Joints.

Dana 35 C-Clip - 27 Spline, 1.18" Diameter Shafts, 7.58" Ring Gear, 2.62" Axle Tube - used '90-'01.

Chrysler 8.25 - 29 Spline, 1.21" Diameter Shafts, 8.25" Ring Gear, 3" Axle Tube - used '97-'01.
Chrysler 8.25 Axles are C-clip.

ABS:
If you have ABS, you have the Dana 35.
Chrysler 8.25 Axle Assemblies did not have ABS on XJs.
Without ABS, you could have either the D35 or the C8.25 Axle.


3.07 Gears- Used with 4.0L Engine/Manual Transmission.

3.55 Gears- Used with 4.0L Engine/Automatic Transmission.

3.73 Gears- Found in some XJs with a Towing Package.

4.10 Gears- Usually used with 2.5L Engine.

Hope this helps.
