i have a dilema my wife figures i should go and spend the money and get a professional to replace the cv axle in our very tired alero (320000) which i may say has been really good to us. she figures that there is a trick to doing this and i say we save the money and do it myself. the only thing i would like to know is do i need a specail tool to do this or is it a clean pull out old one and replace it with the new one?
