Specialist Inspection & Installation Notes
-
Hydraulic Flush: When installing this rack, it is mandatory to perform a full system flush using Pentosin CHF 11S or the official Ferrari-specified fluid. Residual debris from a failed old rack can instantly damage the internal seals of the new unit.
-
Tie-Rod Ends: Always inspect the outer tie-rod ends. While the rack (291133) usually includes the inner rods, the outer ends are wear items that should ideally be replaced during installation for a perfect alignment.
-
Sensor Transfer: Ensure the steering angle sensor (located on the input shaft) is calibrated using a DEIS or Leonardo diagnostic tool after installation to avoid “Manettino Failure” or “ESC System” errors.
