Lots of talk going around about replacing the rear sensor to correct ABS light coming on issues. Gonna throw in so info that might eleminate some hassles for ya.
Recently I had a situation where the ABS and BRAKE lights would just flash one and might not see it again for a couple of days. The other morning I noticed them coming on and going off, usually for a couple of seconds at a time. There were no other indications other than those two lights. I came on home after work and noticed that the truck would want to pull a bit to the right every now and then. After getting to the house, I noticed that the right side brakes were much hotter than the left side. OK, looks like a caliper sticking. Went and picked up a couple of calipers, pads, and brake fluid and got ready for a change out. Pulled the front wheel off and noticed very scorched metallic objects up on the axle housing. The front wheel bearing has completely shelled out in just a couple of miles. $306 later it's fixed. Now for the theory;
On four wheel ABS, there is a "tone ring" inside the front wheel bearing hub. The ABS sensor mounts on top of the hub housing and has a probe that rides close to the tone ring. I think the flash I was getting was one or several of the roller bearing coming unglued and depositing metal on the tone ring or sensor and causing a loss of signal. When the bearings really started coming unraveled, the debris basically "shorted" out the sensor causing it to think the wheel wasn't turning.
If you start to have a ABS light issue, check the front wheel bearings. Mine completely shelled out in just a couple of miles and it was only in the last couple hundred yards that real symptoms started showing.
Now for the $$$ part. There is, for the most part, three different type hubs on the 2500's. The Dodge part number for mine was 5015282. This was a base hub with no sensor or wheel studs. The "price" was $360 for the hub and bearing, $bolts7.95 EACH for the studs, and $36.00 for the sensor. We are looking at $480. Now then, part number 5015282-AA is COMPLETE. Wheel studs and sensor are already mounted. List was $360, but since I was in uniform, the dealer knocked off 25% and got it for $270. It's a piece of cake to replace. Pop the calipers, then the caliper mount, pull the rotor off, the four bolts for the hub. 8 lug bolts.
and 8 other bolts. About an hour and a third of a six pack.
Sorry for the ramble, but this is what I found.
Since I'm headed out to Ft. Carson (again), could someone come by the house and slap on a couple of new calipers ($68 each, TRW's) and a set of pads ($50)? Got a gallon of brake fluid in the floor and all the tools you need. There's a 12 pack of cold ones in the fridge and if you show up before 1800, the better half will feed ya. Call ahead of time and she might just put on a big pot of beans and cornbread for ya. Or maybe a big mess of collards. You might have to bait a hook or two if the g-kids are down at the creek fishing.
Gotta get around and get to the airport.

Glad you got it fixed SR, sure was an expensive little intermittent light though I would be happy to slap those rotors and pads on if you were a wee bit closer. Baiting hooks for G-Kid's is my specialty

Man that meal you describe is purt near worth the trip to Arkansas Have fun at Carson! and look out for that Rocky mountain High
