My current challenge is the steering rack; to eliminate the hydraulic pump, I
am also going to a manual rack, but that is not so easy in this car. Audi uses
a rather strange arrangement where only one end of the rack is used for output,
with both tie rods connecting at that point. It is interesting, as the nominal
position puts the tie rod inner pivot point right on the centerline of the vehicle,
but it is also difficult to replace for that reason.
I experience quite a bit of bump steer with the stock configuration, and I would
like to fix that, so I am currently making lots of measurements, etc to perhaps
relocat the steering pickup on the front suspension. This has become a major
What car is this for?
If it is for an 80 or 100 style body, you could probably get a rack
from a European 4 banger. They normally didn't have power steering and
used vacuum PB.
