Removing C-clip on passenger side rear Axle shaft for 94 ford E-150?
the link to the other question is exactly what you need to do. in the rear end itself, you will see a large pin in between the two ends of the axles. that has an 8 mm bolt head holding it in. Remove that bolt and slide that pin out. Then you can push in the axle far enough that that c lip will fall off. I use a magnet pickup to pull it off. then slide the axle on out! Be very careful when pulling axle out, there is a gear around the axle end and it will try to fall out. Pay attention to how it sits with its washer so when reinstalling you know how to set it back in.
