yeah, I would speculate a wheel speed sensor. next step would be identify which one. that will require seein scan data. if you want to guess at it,which im not a fan of, change the one in the rear dif for the rear wheels, I always found this the most common to fail with dodge trucks. sorry didn't see your post that you have pulled the fuse. you can check sensors at the wheels with an ac voltmeter. but would need something to spin the wheel at a consistent low speed....its harder than it sounds and can be tough to detect
