Are you talking about the spider gears (US name)? I think that they can be changed while in the car but don't hold me to it. They are important in that they allow the rear to turn without sliding the outer tire or spinning the inner tire. In a turn the rear tracks on two different radius.When they break the car will no longer move. (ask me how I know)
Good luck and how is the motor home coming along?
