[DeTomaso] Steering rack spacers

Adjusting the screw will likely do nothing for your problem and may start a leak. The no-return situation is probably due to either not enough toe-in, or not enough caster, or both. In other words, a front alignment problem. You want about 1/8" toe-in, and the max camber you can get stock is -2.6 degrees. Many of us modify the upper front a-arm bushings to get -4 degrees or sometimes a little more. MUCH better at higher speeds. My 2¢- J DeRyke

Hi,

OK, thanks to all for suggestions, will do this and try to get arms
parallel
to the ground.

As well, once the new rack (it is the one for $119
of e-bay) was installed I
find steering very direct (no play), so GOOD, but at
same time VERY stiff.
Basically, the wheels will not return alone to straight
and also, when the
car is on the lift, it is really hard to move the wheels
from left to right
by the hand.

Hove someone had similar experience with
this racks?
Should I try to loosen the adjustment screw that is on the rack; I
seen it
was painted over so supposed the rack was properly
pre-adjusted?

Thanks a lot,

Robert

I recommend that you check the angle of the
steering rack arms to the
ground.  If they are close to parallel, your about as
good as you are going
to get.  You are aiming for parallel to the
ground.
