Bushing was wrong way round! That fixed it. Thanks

Guys, My 10 year old is having some issues with his Unimog and is frustrated. I noticed two things: 1. When you push the Unimog gently forward, and let it go on a flat horizontal surface it rolls back. 2. The gear in the central diff seem to be rubbing on the yellow cylindrical tube (see attached file). Is this normal? Help and tips (besides dismantling it completely ) are welcome.
