1992 Ford F250 front axle

you have failed to tell me if you have a Danna 35, a Danna 44, a Danna 50, but thats ok you also failed to tell me if you have automatic hubs or manual hubs, but that's okay too, since you did not ask how to move them, I will assume you know how, once you have removed the hub and striped the knuckle down to the axle, you will need a slide hammer, unless of course you're Mr. bad, to pull the axle out, it will come straight out to the knuckle, make sure you replace all seals before reinstalling.
