I need to replace a rear cv halfshaft in my 96 legacy because it has a torn rubber boot.  I have a couple questions though...how do I get the axle out of the differental???  Does it just pull out or is there an internal c clip within the diff?  ALso, is it ok if I gently pound the axle out of the hub? 
  
You guys have been a great help before.  Thanks again
