Start by using the pressure washer at your local car wash. Wash the mud that you can see. Then kneel down next to your rig, and wash the bottom of it as best you can with the pressure washer. This means the inside of the wheels, the axles, the coils, the springs, the bottom of the tub, the frame, the cross-members, the control arms, you name it.

Unless you have a lifted rig on some seriously big tires or are on a creeper underneath your Jeep, this still won't get all the crud off. Step 2 (for me at least) is driving home and putting a sprinkler underneath your Jeep. I like the type that waves a series of stream back and forth continuously. The mud softens up when wet, and the repeated sprays of water will wash away most of it. Move the sprinkler around to make sure that all the various sections of the undercarriage.
