[DMCForum] Re: Steering rack adventures



Andrew - As far as the steering rack installation goes, are you sure
that you got the new rack correctly nestled down into the rubber
clamp blocks so that it is correctly positioned laterally?  I did a
rack change on a friends car last year, and it was a bit of a
challenge to get the rack properly situated in those rubber blocks. 
If the rack was shifted one direction or the other, the symptoms
would be as you describe.

In terms of the "camber" issue, I would remove the rubber donut
bushings from the sway bar to lower control arm connections on both
sides.  I think that you will find that the rear-most bushings are
shot.  The rubber tears away from the steel sleeve, and this allows
the lower control arm to drift back, creating the illusion of toe-
out.  Your caster will be off as well.  It's not really a caster
problem.  I replaced my bushings (which were as I described above)
with custom polyurethane bushings.  It made all the difference.
