If it were me, I'd just rebuild the whole front end components and be done with it. Call Cruiser outfitters or Valley Hybrids and get the stuff.
I just did, knuckle rebuild, tie rod ends, brakes, rotors, studs, hubs and then just reused my cheap steering stabilizer. you "shouldn't" even need a stabilizer if everything is good and in spec on the front. An OEM steering stabilizer is pretty cheap. Those other parts for the Aisin/Asco and birf clips are dirt cheap so just do that as well. I also upgraded the axle seals to the marlin crawler seals. Replace the wheel bearings as well, just baseline that whole front end and be over with it. Might as well put new lug studs as well. This way you know you don't have to do it again for awhile.
I'd also plan on replacing those
pogo sticks shocks. Bilstein makes a good setup for the FJ40 thats not too expensive.
Are you lifted at all? If so, you probably need axle shims if you don't have them to get your caster back in spec which could be contributing to your death wobble.
Cruiser brothers aka valley hybrids in Stockton, CA, has a great set of steel shims.
Personally, I've never used the SST for the front end. I've always been able to re-use the shims and so far everything is good on all my rebuilds. You will find varying opinions on this, but if you are able to reuse the shims, it's seems it almost always comes out correct.
Heck, thats just basically the front end. You still have the rear to deal with, then the middle, then everything...
