Rear upper control arm and ball joint replacement

Good afternoon,

The vehicle will have to be lifted by the frame. The suspension needs to be unloaded for this procedure.

Below are the procedure and the pictures for you.

Thank you very much Roy.

You are welcome.

Always glad to help.

Roy, one last question. I will be replacing the ball joint also. Will there be enough clearance (length of bolts on differential) to remove the arm and ball joint assembly or is it necessary to disconnect ball joint from arm prior to removing the 3 bolts on the differential?
Thanks in advance..

You will need to remove the arm first. Then you will have access to the ball joint.
