    OK, I replaced my bad u-joints and everything else is good in the front end, but there was WAY too much play in the thing.

    easy problem to solve right??? I adjusted the steering box twice, and after 100 miles or so the things has loosened up again.

    what up with this?????? (the first time it was adjusted was by my mechanic)

    things that make you go hmmmm!
    is the lock nut on the top of the gear box staying tight or is it something internal?


    It needs a bigger motor.
    what's in it now?

    the lock nut on top is staying tight. it feels just the same when I loosen it so I can adjust it again.

    Are you sure that the play is in the steering box? If you look at it while someone else turns the wheel the steering input turns without the pitman arm turning?
    If it is in the box there are 2 adjustments that can be made:

    Sector Gear Lash: the one that usually doesen't have to be done (the one on top with the allen wrench) and is ususlly the one that people adjust (because it is easer to get at and they often don't know the other exists). This adjustment if over done can be dangerous! It can cause the box to lock in a turn if the gears are too tight.

    Worm Shaft Preload is the other adjustment. It is under the rag joint. There is a large stamped steel locknut that you have to loosen and than tighten the inner ring with a spanner wrench or a screw driver and hammer. Tighten it about 1/8 of a turn and see how it feels. It doesn't take much (like wheel bearings).

    The worm shaft is the one that the steering column attaches to. It has bearings on either end and those are what is adjusted. The sector shaft is the one that the pitman arm attaches to.

    man all I can tell you is that when I make the adjustment on top it solved the problem 100% so I don't know if I'm gonna mess with the one on bottum. I just can't figure out why it keeps loosing adjustment, and I'm not sure how the bottum adjustment would affect the whole scenario.

    If the bearings are out of adjustment adjusting the gear lash will press the bearings to the side "fixing" the prob. The way I was tought to adjust the gear lash was to adjust the sector shaft preload first and then adjust the gear lash. Doing it right even requires a in-lb torque wrench on the steering wheel.
