I decided to take a few pics of the PS cap swap I did. I was in the dark when I started this install and kinda wished I knew what I was getting into. This install is so simple I would say it's a good 20 minute job. I had already installed the JKW cap on my 2wd box so these pics are from a 4wd box I had laying around. Here is where you stick the punch to loosen the snap ring holding the cap in Use a little pair of pliers to pull the snap ring out Here is the ring. It is split where my fingers are. The ring is not very stiff so its easy to get back in place. Now, my 2wd box is almost new so all I had to do was turn the input and it popped right out. I had the top cap off the 4wd box pictured so it wouldn't build any pressure. I put in a self tapping screw and pulled it right out with a crow bar, NOTE** If you use the screw trick make sure the wheels are centered, the piston is forced all the way to the front of the PS box if it is turned all the way to the ......umm......Right I think....Or left...right or left so make sure its centered or the screw will hit the piston and not go in that far. (I assume no liability of you break your ****!) Here is the piston of the 4wd box, see that "O" ring in there? Don't forget about it. Make sure it dosen't get all stove up in there when you put the new cap on! So now you pop the new cap on and replace the snap ring. I used a small hammer and a small cold chisel to persuade it back in. No photos of that sorry. Now onto the top cap. 4 bolts hold it in as well as an adjusting nut. Then the top cap unscrews from the adjuster doohickey. Here is the backside of the top cap. You can clearly see the indentation where you need to drill I screwed up the first cap trying to drill it by hand. That was a mistake. So take two I used a drill press. Duhhh, shoulda done that to begin with. I used a 3/8" NPT tap which required a 37/64" drill bit. Yeah, they don't sell those at the Home Depot. Like buttah Done. You can find pics of the finished product at JKW or EMS offroad. Again, don't blame me if you wreck your ****.
