Re: Scrambler rear axle upgrade, opinions?
Duane D, go find a Scout rear axle with the same ratio. They are only 2" wider per side (not even noticeable), have the same bolt pattern, the pinion yoke is 1/4" different (no need to use another driveshaft), and all you'll have to do it move the spring perches. I've done a few for friends and it's the easiest upgrade you can do. They are plentiful up here, like $100 each, and it'll save you the $$$ from trying to upgrade the AMC 20. However, if you have a lot of $$$ into the AMC 20, keep it, as it's comparable to the D44 when modified (1 piece axles).
I'd ditch both axles for something better. By the time you spend the $$$ on regearing and the 1 piece axles, you could have swapped in something beefier. I swapped in a pair of Scout axles with 4.10 gears in them. The front takes a little work, but it's worth it. You could also find a D30 with better gearing (3.54's are VERY common, I have 4 or 5 of them laying around) and a 3.54'd D44 is also pretty common.
