pull drum off, use the hole in the axle to remove the 4 nuts (unhook E-brake)



Remove the Axles

and just swap whole complete plate

To remove the axle do I just pull the shaft?... or do I have to open the pumpkin?

For the 9-inch c-clip axles yes you have to open the pumpkin. For the 10-inch I don't think you have to open the pumpkin. If you're just putting the 9-inch brakes on non-c-clip axle then you shouldn't have to open the pumpkin. They use that bolt-on plate behind the brakes to hold it in.

The c-clip is only gonna be on the axles with the smaller 9-inch brakes, which I think they don't have fins on the drums. The bigger 10-inch brakes were used from 1987 to 1989 if I remember right, they have fins on the drums and no c-clips.

The c-clips are on the very ends of the axle shafts inside the diff, inside the pumpkin. Should be almost right up against the cross-pin. But since you have the older jeep, you prolly don't have the c-clips to worry about. So its just swapping the brakes right across just like in the pics above, far as I can tell.

Here is something for thought. The larger the brake the better. So you might rethink what you are doing.

^^^ Yep, I was wondering bout that, but I guess he wants to keep the 9-inch stuff since he already bought it.

See post # 9. If you have c-clips they will be on the ends of the axles, circled in red in this pic:
