I found out what it is. you know the little black plastic washer things that are on the shaft that the upper a arm is on??? well those were hanging down so when id turn the screw on the turnbuckle would hit them. I zip tied them so they wont move around. problem solved.

also dagass i heard that your going to be getting a o.s. .21 rg soon, let me tell you they are awsome. my buggy is faster then grease lighting in a bottle.
