I used the craw for the first time today and even though I new if would be making some noise I still was surprised at how much noise and vibration associated with this function. It sound like the Titanic was going down. I was not using it for rock crawling but on a lose rocky road. I will probably never engage this function again. How the hell can you concentrate on driving with all that racket going on? very uncomfortable sound IMO
At the higher speed settings it sounds fine, it seems to be just at the lowest speed setting that it sounds like all hell is breaking loose. I think that setting is really meant for VERY steep descents.
