The C-clip, which retains the axle, is located inside the differential carrier. These photos were shot with the housing out of the Jeep, but the kit can be installed with the housing in the vehicle. With the Jeep on jackstands, remove the tires and wheels and the brake drums. The cover is pulled, and the oil is drained and properly recycled. Slide the axleshafts inboard, which allows the C-clips to be pulled out with a small magnet. With a few special tools and a little experience, the axle upgrade kit can be installed in a few hours.
