[DeTomaso] steering rack....Again??!!Bump steer and noises

[Will Kooiman]

Rattles, creaks, and groans?

What about the wheel bearings?

What about the rotors and pads?

Personally I would suspect a suspension problem. Mechanical feeling can
easily be transmitted back through the tie rods, rack and be felt through
the steering wheel. Did your suspension rebuild change anything geometry
wise, is something binding when the suspension is unloaded now the rack is
lower? Did you check the sway bar mounts during the rebuild process they are
known to crack in two allowing the sway bar to move. As Doug says trying
moving it all around, maybe also try that in different unload positions i.e.
wheels free from the ground, on ground suspension partially unloaded to see
if you can detect/reproduce the problem.
 
Good luck,
Julian
