I am just curious how this is done i have already removed calipers and rotors.
any help would be great

 

You have to open up the differential. Remove the carrier pin bolt. Remove the carrier pin. Remove the spider gears. Push the axle you want to remove in toward the carrier, this releases the c-clip in the diff. Remove it and pull the axle out.

OOOOPS, realized this is dodge section Same may still apply.

 

If it is a C-clip axle pretty much everything that KYSilverado said, except you don't always have to remove the spider gears to get the c-clip out, if it is a full floater you need to take all the bolts off holding the hub on at the end and then pull it off.
