well for one thing it works, and you rarely have to work on them. I bought my truck in 1984, aside from changing oil a couple of times. I have never touched it. As a matter of fact it wasn't until about a year ago that I looked to see what was actually involved back there. It is actually a pretty good set up, since everything is sealed up, unlike the open drive line where the universal joints are exposed to any and everything you happen to drive through. Actually I haven't touched much on the whole truck........
