Help with steering box ?

[Planohummer]

The odds of you finding someone who can actually rebuild/reseal a steering gearbox and reset the pinion depth are pretty slim. Do a lot of inquiring before you let somebody go into it-you could end up a whole lot worse off.
Just a thought--have you had the alignment checked?? Too little caster will give you almost no steer-ahead and make the truck 'wander' on the road.
