Nero problem !!!

I have a problem with my nero. Doesn't work. goes only when the climb mode. When different modes goes only very slowly and make strange noise.

Sounds like maybe your rear output pin is broken. No power to the rear wheels. Start looking at the back of the center diff and work back from there.

Yapp, that sounds like maintaining the diff´s.
If you do so, check for space while mounting and shim them. It will hold longer because of less worn out.
