Just replaced the upper control arms on my 2007 Dodge Ram 2WD. My truck had 140,000 miles and it was time to change them. Taking the old one off and putting this one on was easy. 1. Jack up the loader under the lower control arm. 2. Use jack stands for safety. 3. Remove the castle nut that secures the control lever to the steering knuckle. 4. Remove both upper arm bolts. 5. Knock the upper ball joint with your knuckle to pop it out. 6. Remove the control handle and install a new one. Remember to tighten the upper arm bolts when they are parallel to the floor. Do not tighten when the upper lever is in the down position. My truck drives 100% better. The best steering. Smooth ride. Make no mistake with the Moog.the CK series. O. Don't forget to mount the oiler and apply lubricant
