Have a lot of slop from the gearstick on my ra can see where it has the play in it but not sure if it can be sorted with the box in the car.

Does anyone know if i can remove the nuckle and the shaft at the box its the bit with the pin through it its the part on the very top left of the pic part 4 and the pin 3
really dont fancy taking the box out if it can be done in situ on the car.
Cheers
