Looks like you will just have to wait for it to happen again and try to pin point exactly where its comming from. I wasnt to worried about it because I off road all the time and it has only happend a few times.

Mine has done it more times than I can count. Usually when I'm playing in a lot of water or wash the under side of my Jeep. It's shortly accompanied by my Christmas tree dash light Service 4wheel drive/esp/abs/brake lights. Each of the last 2 times I went out a different DTC code came with it. First time was U1417 Left Speed Sensor then the next time was U1418 Right Speed Sensor.
I have a video from November Jeepskool that shows me getting sideways down a muddy trail. The faulty speed sensor was causing my esp to override and control my ABS. Which in turn was pulsing 1 front brake and 1 rear brake trying to straighten the truck out. Each time the abs released it caused a loud pop noise. It's coming from the abs pump itself.
Tonight I just replaced the rear rotors and pads. (yesterday I did the fronts) While I was under the Jeep I dropped my spare down and hosed the year or so of caked mud from under it. I must have used 100 gallons of water. Went to take the Jeep for a ride to cut in the pads and guess what came on? You guessed it. Abs was popping like a drive by in Compton and again it was code U1417!! Just because the connector got wet. Blew it out with my compressor and problem was gone.
Wish we could get a shut off switch like the JK's have. I blame that system for getting me stuck that time.
It might be time to wire in a kill switch of the ABS system I think.
on the JK's we bypass the traction control and ABS system with a simple toggle switch on a wire, especailly with the superchargers installed.

I did the same thing to bypass the traction control on the XK. I have a toggle under the dash hooked to the ABS pump fuse under the hood and when I flip the switch It totally disables the Traction Control. I dont use it very often but I think once I get a locker in the rear ill use it more.

I haven't look at how to do this is there only one fuse I take it. I know I can figure this out but maybe a pic or two will help to see what you guys have done.
Here are a few pictures I took when I installed the switch.
