I gotta just chime-in
There are way
too many guys, with bad steering components (idler arms, tie rod ends, etc), who think it's OK to just "crank away" on that box. It is a STUPID fix that is recommended way
too often here....
merc123 is ABSOLUTELY right! If you indiscriminately crank down
on the adjustment (easy to do) you are binding the gears up and will ruin the box (which is probably OK in the first place) and risk losing the ability to steer properly.
Only after eliminating the possibility of the "slop
" coming from one of the Many joints in the steering system, should you even consider
adjusting the box itself. Have somebody rock the slop in the wheel back & forth while you compare the amount the input shaft moves with the pitman arms movement, and realize, There SHOULD be some "slop".
clearance between the gears (just like in your diff, you'd never
shim that up Tight - right?
Any adjustment you make should be slight, and STOP and BACKOFF if you lose all the slop or feel ANY binding (wheels up, off the ground, lock-to-lock)
You're messin' with serious stuff here,,,, don't screw around
with Brakes or Steering!
