I stripped them all the way down first, cleaned and reassembled the Aisin hubs. Just waiting to get them back from the machine shop, and for the Toyota reman CV shafts to arrive at the dealership.
Where we'll try returning some ADD/fixed hub shafts as cores to see if they're OK with that, and keep the rusty/crusty manual shafts that came with the hubs as spares to take with on our long summer trips. Since they're a bit harder to find, apparently.
I briefly entertained the idea of replacing the ADD passenger leg on the diff with a fixed Tacoma left (plain tube and a solid shaft), but... more effort for very little gain.
I may still disable the ADD, and leave it in '4WD mode'. One less thing that needs to work out on the trail. Just lock the hubs, and engage 4WD with the manual transfer case shifter, no electronics, no vacuum involved. And just a light bit of rewiring to make the dash light turn on/off based on the 2/4 position switch in the transfer case, instead of the ADD position switch in the front diff.
Or... not. It's even easier to do nothing and leave ADD in operation. I've never had any issues with it over 12 years of wheeling with it.
And once the manual hubs are installed, I'll crank the front ride height up an inch or so, level it out with the rear. It's a SS 1.2 with the Radflo coilovers, I've kept them a bit lower so far to keep the CV boots from chewing themselves up in everyday driving. With them only turning when the hubs are locked, they can stand some more rib abuse.
