Tow with the front wheels on the dolly.
Drive up on dolly and secure the wheels.
Place the Jeep in park and set the park brake.
Pull the rear driveshaft. Use a 5/16" wrench with a cheater for leverage to break free. You may get lucky and be able to use a 1/4 drive rachet & extension with 5/16 socket to speed the process.
The drive shaft (if not modifed) should just pull out of the case. If the T/C is modified you actually scored a $450-500 mod. The size wrench will depend on which manufacturer's Slip Yoke Eliminator commonly called an SYE.
The fluid should stay in the t/c as the level should not be that high, if the fluid does come out the case was overfull. For assurance you can cap off with plastic bag as recommend in a previous post.
Leave the trans in park, do not start engine of the Jeep. The fluid will come out of an un modified t/c if you drive the Jeep with the rear shaft off.
Double check your hitch, chains and electrical connections.
Release park brake on Jeep and tow home.
Send $$$ to Naxja and join by March 31st for a chance to win an onboard air compressor and get your name in red. (couldn't resist a plug for the club).
Have fun and welcome to

This took me too long to type. What Ketjar & Old Man said works.
