You need a deep 9/16 socket for the top nut, on a swivel would be great. Keep the jeep on the ground and remove the top nut first. Remove the bottom 1/2 inch nuts and bolts (2). Install in reverse order.
Jack up the front end and place on jack stands. Place jack stands on the frame behind the front wheels. Ensure stands are not in a place where they will slip and make sure vehicle is on an even surface as you do not want the vehicle to fall off of the stands, especially while you are under it. Remove tires
once vehicle has been placed on the stands. Remove the top and bottom bolts from the long tubular shock. Then remove the bolts holding the coil shocks on. Because when doing this as there may be tension in the coil springs still. Replace the shocks and reinstall the bolts. This job is fairly simple but can be intimidating if you have never done it before. You will be amazed at how easy it actually is once you have done it. Just be sure to remember how everything came apart and you will be able to get everything back together just fine. You can use the jack to adjust the axle up or down to make getting the shocks out easier.
Repeat for the rear. Good luck
