Rear Upper Control Arm

If you were off road and bent your Jeeps control arm or the bushings have failed and allowed the arm to move around and wallow out the eye, the Crown Automotive Rear Upper Control Arm will get your rear axle set straight. Upper control arms are important to the Jeeps suspension as they keep the pinion angle set on the axle and make sure the drive shaft u-joints don't undergo unusual stress. A bad or bent control arm will allow the axle to reposition itself where it wants rather than where it should be. If you are getting a vibration from the rear you may need to look at your upper arms to make sure they are straight and true.
