In this video, I rebuild my rear axle and change out the axle seals. I got myself the chinese knockoff tool and a Marlin rebuild kit to keep this affordable. I did end up having problems with the tool but I got through it just fine. I don't suggest the copy cat as you'll end up spending more than the original tool (see my link). The video is done on my ABS axle but can be used for non-ABS axles also.

I used information documented by Timmy the toolman's video for many things and changed up just a few things for simplicity and efficiency and also sped up many parts of the video so you just get the important stuff. I also chose to RTV my axle seal to ensure no leaks. Make sure you check his video out also as this video has a lot of great information:
