Our main issues were:
1) When you turn on AWD there is a bad vibration at slow speeds (under around 3mph). It is so bad that you can feel the vibration through the seat and up to your butt. Anyone else have this issue? Since we do lots of rock crawling this is a real issue for use. Also with AWD engaged the effort needed to turn the steering increases dramatically. It acts like the diff is locked up and you are driving on dry pavement but we are on loose dirt and rocks. Our XP 900’s didn’t have either of these issues.
2) When starting out in High gear at a slow pace you hear a clunking in the drive train. It sounds like its coming from the rear- either slop in the u- joint or in the transmission
We had no other issues. They never overheated. We saw 210 max. They have great power. The clutch offers fantastic braking as we descended down the mountains. I am running the Pro Armor Crawler XG’s in 30". So far they work great but it will take some some more rock crawling to make a good comparison to the Roctanes.
Other than the issues above (and the crappy cell phone holder that is too hard to open) its a great machine.
