I did the same a couple years ago, had a axle bearing go bad. Anyway just loosen the bolt that holds the crosspin in the spider gears and slide the shaft out. Push the axles inward towards the diff then your c clips can be removed. Might as well replace seals and bearings while your at it. You will need some kind of slide hammer - bearing puller. Just curious if your original shafts are the same diameter as your new stuff. let me know.
