3:55 to 3:73 Gear Change Help Needed

Could use some instructions to remove and replace C clips to remove axle shafts. Is there any program changes required when changing from 3:55 to 3:73? Any help would be appreciated. Thanks

Unbolt and remove the calipers and brackets, remove the ABS sensors, unbolt the diff cover and drain the fluid, take out the cross shaft bolt on the diff (it's a very tiny bolt the goes through the cross shaft), remove the cross shaft, and then push each axle in one at a time, while using a magnet to remove the c-clip. Then the axles should come out nice and easy. As for the gear swap, you need to reprogram the computer so that the speedo is accurate.
