They are all thin enough, IMHO, it doesn't matter.

Did this today with the Auto Trak II and the harbor freight pump. Very easy even for one person. Thanks for the write up. Worst part was the GM dealer, $9 a quart.

Thanks

Thanks for the great pictures on how to do it, I too was looking all over. I've done it before on other vehicles. Buts it always great to have actual pictures of your own truck to boost the confidence to do it.

Very much appreciated

I have also used a pump that you can get to refill the lower end of an outboard engine. Theses are cheap and the nice thing is they screw right to the top of the bottles of oil. Check out the link, unit is 2nd from left top row.

I want to say a big to the thread author for your time. I really appreciate you making this thread, without it i prob. would have paid $$$$$ someone to do this for me...seems easy enough. Also, thanks to everyone else that has contributed comments, or procedure tips. I'm adding this to my maintenance list.

Transfer case fluid change

Just to add great Thread, I use a cheap pump that attaches to the top of bottle, hard to get all the fluid out what I end up doing is using one bottle and filling it with the others. The transfer case or forward or aft differential are full when the car is level on it's wheels and fluid drips from the fill port(hole) Thanks again for the posts.
