I'm not being critical, but if I was still able to do such extensive repairs & maintenance in a 30-day period, I would've done the work in 5 stages:

• 1) fluid changes: (followed by test run and fluid checks after the test run)
  • a) Changed front diff oil
    b) Changed rear dif oil
    c) Changed the Transfer case oil
• 2) Also changed Transfer case motor (again, a test run to gauge the results),
• 3) Changed steering wheel angle sensor too (also a follow-up test to see what the effect was),
• 4) Front wheel drive shafts have also been replaced (repairing or replacing major mechanical components dictates a test run, too), and
• 5) Front wheel bearings replaced (same criteria, for another major component group)

After many decades of working on hundreds of cars and industrial machines, building and racing some cars and engines I built, I learned to not make too many changes at a time, before I understood the results (tuning, mostly), or changing/upgrading multiple components at a time as well (like changing rear axle ratio, torque converter stall speed, and perhaps carburetor jetting all at once, and racing the next day...with only two test runs).

It takes me 10x the time now to make simple repairs, and twice that to try my theories on my cars, than it used to take. Maybe tht's a good thing, making me slow down. Go slow to make it go, go fast and get passed.
