Default Re: Steering rack and pinion possible problem.

Sooo, the r&p unit is solidly mounted and not moving as you thought? If not the steering rack then you'll have to start from the beginning by examining the steering system as a whole, either on the ground with engine running or up on a lift with front wheels unloaded and free to turn by hand without the engine running. You'll be checking for slop in mechanics from the steering wheel, steering shaft column, connection to the rack unit, tie rods, and wheel knuckles. A steering/suspension expert may be needed to see if there's anything broken/loose/bent/worn.

There aren't any hidden bushings to wear out under those mounting bolts. If you carefully observe how the steering system operates, the chassis holding the steering rack cannot be allowed to move with a loosely mounted steering rack assembly - all steering forces are transferred from the steering wheel to the front wheels with minimum slop through all the mechanical connections. Rack and pinion steering is the ultimate in steering accuracy.

REWARD EXCELLENCE!
