- 1). Attach the inflation/needle tool to the valve on the shock and bleed all of the nitrogen from the shock.
- 2). Clean the outside of the shock with brake cleaner and position the two shock blocks on either side of the body. Place the shock in a vise using the blocks to hold the shock in place.
- 3). Remove the bottom of the shock and the bleed screw from the floating piston. Remove the piston and pour the oil out. Pumping the shock will assist in removing all of the oil. Disassemble the other end of the shock and clean all of the components with clean rags.
- 4). Examine any of the wear parts such as O-rings, seals and pistons. If there is any pitting, grooving or abnormal wear, replace with a new Fox part.
- 5). Tip the shock at an angle and fill with new oil. Move the shock rod up and down while maintaining the valve stack in the oil. Move the rod slowly until no more air bubbles come out. Leave the rod in the fully extended position.
- 6). Place the shock back in between the blocks and into the vise. Gently tap the side of the shock to drive out any more air bubbles.
- 7). Add oil to the bottom of the threads and install the floating piston. Set the depth to the manufacturer's specifications with the calipers. Install the bleed screw and pour out oil above the piston.
- 8). Clean out the cap and install it with a tiny amount of red Loctite.
- 9). Connect the nitrogen tank to the regulator and hose. Fasten the hose to the shocks valve and fill the shock to 200 PSI.

Test the shock by compressing and extending it a few times. A properly rebuilt shock will be smooth and quiet.
