Flipping the carrier over, we get to the more complicated part. This side is held together with a series of stretch bolts that are held in place with pressed on retainers. These retainers can be removed using a small flat tip screw driver pushed under the edge of the retainer to work it off. Then the bolts can be removed. After you finish removing the bolts and retainers... throw them away. These have to be replaced with new components when you reassemble the carrier. Why? Because you don't re-use stretch bolts or their retainers. You can get the new bolts and retainers when you order your new side gears. Lift the top and be careful not to get anything in the rubber seal you can see in the cap. Although it looks a little different, all the parts you need to get to are in the same place as it was on the other side. Remember the thrust washer again, and lift out the side gear. Replace this side gear as you did on the other side.
*NOTE* In the Samurai models (RD72 and RD73) this side gear just drops into place. If you use this article as a reference to replace your rear Track/Kick ARB side gears, you have to disassemble the whole carrier because the larger side gears won't fit through the black 'basket' you see surrounding the spider gears in the photo.Gently drop in the side gear and then the thrust washer. Check the cap for anything that may have made its way in there and replace the cap.
