The front axle will not work, the scout differential is on the opposite side than your stock axle.
Otherwise they're pretty easy to install. The wheel lug pattern is different also.
If you want some good d44 axles that are relatively easy to install, look for a front d44 from an '80s Grand Wagoneer (SJ) and a rear d44 from a mid '90s Isuzu Rodeo or Honda Passport. These axles have a matching 6-lug wheel pattern, wheels are very common, and it gives you 4whl disc brakes.
