power steering

i have a 78 bronco that originally had the 351M but was swapped for a 429. the power steering (pump and gearbox) are the ones from the 351M. i just rebuilt the gearbox b/c it blew out the bottom seal. My problem is, now that the steering is like new (kinda loose) it allows you to oversteer too much, which can really be a problem on small roads. my theory on this is that the bronco has 33 x 12.5 tires on it (the original tires were much smaller) but i think the steering stabilizer shock is still original and is not strong enough to return the wheels back to center. any help would be much appreciated

Check you caster alignment. If the caster is correct, you shouldn't
have trouble returning to center, and it driving straight..

The stabilizer acts like a shock absorber, it does nothing for
returning your stearing to center....

Agree with Bob. The stabilizer was not factory equipment, so they were never intended to return the steering to center. All they do is help reduce the effects of the larger tires "bump-steering".

if this was noticed after the gearbox rebuild i would first look at you sector shaft preload, this sould have been set during the rebuild but what you can do now is to loosen the preload nut onto the gearbox and backoff (counterclockwise) the sector shaft. go maybe 1/2 turn at first as it doesn't take mutch. then tighten nut and drive again. if it seems as if it's getting better try a little more, too much and you'll get a steering wondering concern. hope this helps.
