You will have to slide it straight out. If you use a hammer, be careful not to damage the threads. Replacing this part is hard to find. Tip: If you are going to use a hammer, slide a Ύ x .090 wall tube 2- ½ inches long over the shock stud. This will protect it from damage. 3.

Installation
requires the rear of the vehicle to be lifted off the ground. Support the
vehicle on the frame. Lift up the rear end high enough to allow the
suspension to go full droop. The springs must be removed for lower arm
installation. Tip--- After the frame is supported, begin to lower the
rear-end. Just before the shocks fully extend remove the shocks off the rear
end stud. This will allow the rear end to lower far enough to remove the
springs. With the rear end in full droop remove the springs. The springs
should slide out without too much trouble.
bearing side to the frame. Make sure the bearing has a gold sleeve
(installed from our factory) still on each side of the arm. Slide the
assembly up into the frame and use new hardware supplied in the kit to
install. Place a 5/8 flat washer on the bolt first, slide the bolt through
the assembly and then another flat washer / nut. Torque the bolt to 90
foot-pounds. 
Swing
the other side of the lower arm up into the rear end. Make sure the parking
brake cables are above the arm. Install the shock bolt through the hole so
the flat is facing the back of the car. The shock mount will index in the
rear end bracket. Do not torque yet. Install the lock washer and nut on and
slightly run it down.
