I'm newbie here looking for some help. My belt was slipping so I changed it out and cleaned the clutches the best I could. Ran it for a few short rides and the belt started slipping again. So I put the ranger on blocks and took cover off of belt to watch the clutches to make sure they are functioning like I think they should and they look like they are. But when I accelerate it faster the rear end pops and jerks at about 3200 rpm's. What could be causing the belt to slip if the clutches are opening and closing and it's a new belt? Also what would cause the popping and jerking?
