You will need a compressor and takes a bit of time. As a tech I typically use this on my front Diff service. Doing it in 70+ weather helps it go faster. I run Amsoil 75w90 and get the bags so it helps filling. Here’s also a link showing me doing it on my old F-150 if you wanna get fancy get a barb fitting and a piece of 1/4 plastic air line tube. To get to the bottom easier This yields about a 80-90% fluid exchange and saves the hassle of dropping the diff and pulling the cover. Also works on the rear too.
