I have a 2005 RTV900. If I put it in 2WD the motor just revs, if I step on the diff lock it runs fine. In 4WD it moves fine too. However it does seem to be down on power in uphill climbs in the 4WD setting. Any ideas? I was going to put it in the air on all corners and see what I’m getting. I’m suspecting that without the diff lock engaged I’m getting no rear drive, but with it engaged I’m only getting one rear wheel engaging. If that’s the case does it point to a bad axle in the rear? Also with the 4WD engaged is the front a limited slip? It seems like only one side of the front end is rotating whether the other side is slipping or not.
