Problems with pulling to the right,, please help!

[MeatWagon]

I'm starting to think it's something we have to live with . I put a new caliper on the passenger side a while ago and it still pulls . I'll let you know how it does when I do the driver side . But first I have to replace the crappy auto hubs . I blew one last saturday . I'm going with Mile Markers . Hope it doesn't snow before they come in !

Same problem but, fixed

Its kind of a weird theory but, The air pressure in my tires mad ethe pull on mine. It was only off by like 10 psi but it sure made a heck of a difference. Just a thought im not a whiz

no,, definitly NOT something we should have to live with,,,

these trucks rolled off the show room floor tracking straight,, they did at one time they should be able to be restored to that state.
next thing im trying is to replace the Axle beam pivot bushings,, i dont ever see anyone talking about this being a possible fix for the pulling problem.
this could absolutly cause the problem!

mrboyle - you da man !.
To quote:
>> The pull you are experiencing is due to the worn radius arm bushing (mine is dooing the same thing currently). What causes the pull is when the bushing on the right side wears it allows the end of the radius arm to rotate up. This rotation causes you to lose caster on the right side, which cuuses the caster split to be off. The vehicle will pull to the side with the least amount of caster (right in our case). <<

Was exactly the problem. Had the RA bushings changed (for Moog ones). Then front-end re-aligned, and it tracks pretty straight now.
RA bushings LOOKED fine, but the center of the passenger-side bushing was badly chewed-up. Driver side seemed OK.

Took the opportunity to reduce steering wheel play by *carefully* adjusting the steering box preload.
Much better to drive - like it rolled the clock back to 1996....
