Hitec HS-7954SH Servos Grinding

Bought a 2nd hand 2.6m CARF Extra 260 equipped with HS-7954SH on the wings and tail surfaces.

They work fine but make a grinding noise... a bit like a manual coffee grinder does. Pushing lightly on the related surface whilst moving it and one feels the teeth. Still moving the surface but pushing harder on it and the grinding is less :confused:

- is this normal?
- wear?
- advice?

My guess is you need to replace the gears
