well, i dunno if yours has a hp or not, but my 98 cherokee has a hp30, just look to see if the centerline of the yoke/pinion is above the centerline of the axle shafts...

2000 and 2001 XJs have low pinion D30s; all other years have high-pinion ones.

that may be the reason for the difference in fluid needed.

2000 and 2001 have a low pinion D30. All other years have a high pinion D30. I just fill it until it won't hold anymore.
DJKS Dana 30 ( 181MM ) Front Axle = low pinion
DRMP Dana 35C ( 194MM ) Rear Axle

Googling 186FBI only shows hits for WJ D30 axles. 181FBI just showed XJ hits. Still not sure what the difference it though.

From the FSM
The 181 Front Beam-design Iron (FBI) axle consists
of a cast iron differential housing with axle
shaft tubes extending from either side. The tubes are
pressed into the differential housing and welded.
The integral type housing, hypoid gear design has
the centerline of the pinion set above the centerline
of the ring gear.
The 181 is the High Pinion

2000 and 2001 have a low pinion D30. All other years have a high pinion D30. This is an observable fact.
There may be a typo in my Build Sheet that I got from ChryCoJeep based on my VIN number. I have seen typos in my FSM, like the example picture of the ZJ 318 V8 fuel rail instead of the XJ I-6 fuel rail. Don't sweat the details, just fill 'er up.
If you go to buy parts just make sure your tell the guy high or low pinion. Any good supplier will know what you are talking about. Wranglers use the same low pinion axle. About the only things that will be different are the ring gear and pinion gear.
