How to Remount a Truck's Upper Control Arm

Video Transcript

"Hi my name is Nate McCullough on behalf of Expert Village. In the following clips we're going to talk about the correct procedure for replacing your upper and lower ball joints on a two wheel drive full size vehicle. In this clip we're going to talk about insuring you have the correct control arm and alignment of your mounting bolts. The control arms are a right and a left, they are not identical. They are not asymmetrical as you can see right here next to the ball joint grease boot there is an "L". That indicates that this is only for the driver?s side of the vehicle. How you determine which side of the vehicle it is you picture yourself sitting behind the steering wheel, your left hand is going to indicate the left side and your right hand is going to indicate the right side. We are on the driver?s side front, got the left one, indicated here on the casting of the control arm and we're going to take and set our control arm up into place. Previously in another clip we indexed our cam adjusters. You are going to want to ensure that you put your cam adjuster back where you got it from. Just given the discrepancy and the way you have them marked. I mark mine always in the exactly same spot so I can mix them around. But just per chance if you marked one at twelve o'clock and mark the other one at three o'clock your not going to want to align the wrong index point with the wrong cam bolt. What we're going to do is take and slip right back in here and install our camber bolt. It'll take a little bit of fiddling to get all the proper stuff to line up. Alright once you have the bolt started and through you can go ahead and put your retaining nut on it. We're going to go ahead and do the front one, I might be in your way a little bit here so please a bare with me. Alright we're going to go ahead and start our nut right there. And that is the proper way to identify the correct control arm and remount it on the vehicle."
