I've got a bearing of unknown origin that appears to be 18-spline Mopar. The problem is that most of the hydraulic bearings that I've seen have a bracket to prevent the body from spinning. This one doesn't and I have no installation instructions to determine what will prevent it. The bright ring is threaded to allow for clearance adjustment and it has two heavy rings on the inside that appear to be for tightness against the bearing retainer, but that's all there is. Anybody know anything about this? Manufacturer? The last pic is what I've seen on line of bearings with a way to prevent rotation of the body.
