when running bigger tires, there are a few things you can do to make it steer better. besides the obvious, checking your tie rod ends, draglink, pitman, etc for wear, best thing to do is get rid of the reman box and get a quality built box. the quality of a reman is a crapshoot, and bigger tires will find any weaknesses in it pretty quick. i switched up to crossover steer about 5 yrs ago and installed a "new" reman box. besides constantly being a leaker, there was a dead section in the steering that i could not adjust out, and i went all new tie rods and whatnot during the conversion, as well as a dual stabilizer.
after blowing the sector shaft seal 30 miles out in the bush (and screwing up my brakes, hydroboost) i decided it was time to get a serious box.
i would recommend replacing your gear with a Redhead steering box. ya, there more expensive than a reman, but do you really want to put a price on losing control of your truck?
belive me, there worth the money. my truck steers 100%, centers beautifully and i can steer the truck wit 1 finger, and this is with 38's or 42's.

a steering brace is pretty much mandatory with bigger rubber. go to a wrecking yard and look for a 1 ton, they come with a factory steering brace that will bolt onto any K square with no mods needed.

if you want your frame to be bulletproof without cracking around the box, think about triangulating your frame. i mounted a piece of 1/4 thick angle iron right beside the fr spring hangers. besides eliminating any frame flex around the box, it also gave me a handy spot to mount a fr receiver for our bike rack.
