456 pulling slightly to the right

my dealer did the geometrie of my 456 and it pulls slightly to the right.
they changed all four dampers (the rear-ones were leaking...) one of the front ones seemed to be dead. when they tried again the car still pulled to
the right. they seem to have a hard time finding the cause of the problem.
has anyone an idea what the cause could be?
thank you for any help.

 

Check the inner tie-rod ball joints. Mine were completely worn by 20k miles. This heavy, front-engined car results in accelerated wear to the front steering components. Should check the other ball joints as well. Also, my steering rack was both leaking and slightly loose. I had it rebuilt during my recent valve-guide replacement.

If you find loose inner tie rods, check my prior posts for an inexpensive replacement source.

 

thank you diablo,
the only thing is that i have no idea how tie-rod ball joints translates in french...!!!
can anybody help?

 

Here's a description with pictures. The pictures show the tie-rod with the ball joints on both ends.

Hope this helps. This may have nothing to do with your steering geometry problem.

Just to be sure, you also want to check tire pressure.
my 550 was pulling rght under accel. I had a slow puncture.
