Hello.
EDIT: It's done. Remove both shaft bolts from coupling. Loosen three bolts holding steering box to car to make space (move steering box from the firewall a bit). Remove bolt holding steering shaft under the dash board and shift the shaft towards the steering wheel. This will make enough space to remove the coupling.
I have a rattle in the steering coupling. I got new one from MB. Is it possible to replace it without removing the steering box? On 6.3 it's possible to remove the steering wheel and move the steering shaft upward to make space for removal. Is the same possible on 600?
Thanks
Filip
