Ok so I have been scratching my brain all day on this problem. I hit a tree with my rear tire and bent my rim on the outside lip. Then the tire has a wobble to it, thinking it was the rim I purchased a new one, it still wobbles with new rim. I looked at a arms and spun the tires while jacked up in the air. After I took the tire off and spun the axel I noticed the roter is bent and the break caliber is moving in and out, so I take off the hub and roter. I closely examined them and they do not appear to be warped or bent to my eye and I played them down on flat surface with the same outcome it appears to be straight. Any suggestions?
