But to get all the fluid out - the truck will have to be completely inverted - turning it on it's side won't get all the fluid.
Okay, really - get a fluid sucker - they are different than a Tootsie Pop - and suck it out. The one I used (I don't know if there are different types) requires you to suck some out - dump it in an approved container - suck again - repeat process until empty.
The shitty thing about the job is getting all the fluid out. After you get to a certain point you can't get any more fluid out - even though you haven't taken much out at all. What I found was to work is to insert the tube - have someone spin the wheel so the ring gear rotates - you will feel the tube drop in further. Suck again. It is more time consuming than it is difficult.
