Pretty sure that is all one assembly with the sector shaft.

As mentioned, you can also try changing/removing shims at the plate above the worm gear shaft. Might help find a less worn contact patch with the sector shaft.

Isn’t that shim for the preload on the bearings on the ball screw (worm gear)?

Aaah that worm gear wear maybe not so much that other one.

For sure. But I think it also impacts the way the gear teeth mesh and align so you might find a different pattern that reduces some of the slop.

Can you flip the ball nut over 180 deg? That might change how the sector shaft and the ball nut mate.
