Accidentally broke the fancy funnel while changing the rear diff fluid so I rigged up the following quick fix gravity feed that worked great. You will need the following items: five feet or so of 1/2 or 3/4 clear tubing, tape, push broom. Cut one end of the tubing at 45 degree angle and insert in rear diff refill hole. Place the broom upright behind the rear passenger side wheel well. Thread the tube from the rear diff, over the rear shock and out thru the wheel well. Tape the tubing to the end of the push broom leaving the last three inches of the tubing free to connect your squeeze bottle of choice. Basically a gear oil IV with no mess and no time on your back. Hope this helps...happy trails.
