2nd Gen Non-Engine/Transmission Steering box bearing preload adjustment????

[rmcnamee]

Hello,

I got some questions on adjusting the bearing preload (not the over center adjustment) on the steering box.

1. What does the preload of this bearing effect?



2. If the preload is too much/tight, will it effect the steerings ability to return to center?



3. Where can I buy the spanner wrench used to make the adjustment?



Thanks

Ryan

Ryan,



I just did mine. I used a small punch in one of the holes and another around that punch & across the input shaft as I didn't have a spanner. I tightened it up just snug and didn't return the 1/2 inch spec'd in the service manual (if I did, it would have been looser than what I started with). It definately removed a lot of play I had in the wheel.

Thanks for the input. My box is a new Delphi (dealer) unit and it just seems to be really tight. I'm wondering if the preload is set too high and is hampering the frontends ability to return to center after a turn. I've had this problem for a few weeks now and have since replaced the upper/lower ball joints, box and adjusted the caster (almost fully adjusted) and while it has gotten better, its still not perfect. The wheel returns to center about 85% on its own, then I have to bring it back the remaining 15%.



Thanks

My adjuster wouldn't turn so I tapped it about 5 degrees with a punch to snug it up a little.



The preload is on the input shaft bearing and prevents the shaft from end play movement along its axis. If loose, then the end play in the shaft produces steering wheel play and wander.



I wouldn't loosen it - they have a habit of doing that themselves soon enough.
