I have a dilemma, or at the very least a very disheartening concern: I rode with a group yesterday for about 8 hours, over dirt paths, rocky terrain, river beds, and dirt and gravel roads. I have noticed that the ACE kicks up ALOT of rocks. The constant harmony of rocks hitting the fender wells is music to my ears..I love it. However...I got the Ace pulled up onto the trailer and was looking it over and both of the rear axle housing (metal cylinder tubes) closest to the engine have numerous deep grooves in them as if a rock got stuck between it and the flat piece that sits in front of it. Im not a mechanic and not sure if that's what its called, but Im sure you more savvy posters know exactly what Im talking about. Im wondering if this happens with all Ace's and other ATV/UTV's...I would think there would be something over them to keep rocks from getting caught and tearing them up. While I do realize they are metal, I am positive this is a bad thing! Any input would be greatly appreciated. Thanks
