2005 King Cat track issues???

track tearing

Is their a chance your torsion springs are digging in? The pic kinda looks like they are steep.

The nasty growling, rubbing noise is probably the track driveshaft hitting the bumps. The first time I ever rode a 1M it was doing the same thing. I almost refused to ever ride one again, but the ones I have had since only seem to do it occasionally. Like you said mostly on hard packed moguls. I also had a track that was doing the same thing yours looks like. The previous owner had ported it on the outside belt and the holes ran directly over the idler wheels on the upper rear arm, It was causing the rubber on the track to come loose from the cording inside, then snow and ice would start working in between and made it growl even more. I have also seen one or two tracks that started working the rubber loose over the screw head marks in the molding. They would do the same, let snow and ice in and just get worse. Maybe check and see that the upper idlers are running where they are supposed to and haven't worked out a little. Also check your track tension, if your track is too tight it would make the track pull over the idlers harder and make the problem worse.

Hey Doug

I had same issue on my kk after installing drop brackets with the vibration, what I found was the end of the track rails were hitting the drivers, you can tell if they are hitting by looking at the end of the rail tip and if there are scuff marks, easy fix is to cut the end of the rail back, check out pictures, this year I installed IceAge rails because of cracking on stock rails and I had them cut of the end for me, Goodluck MADDOFWFO
