oh and then vent release for the rear end. do not put it on the center section/pumpkin like I did :P
it goes on the axle tube about 1/2 way towards the tire, facing up.
i could have sworn it was supposed to go on the center section...after about 500 miles i found out all of the gear
oil was pushed out of the differential and it wrecked the pinion bearing. that has been fixed now of course - but what an oops :O
