Replace the axles with reman or new ones. Installing cv boots are pain to install.
My recommendation is to replace the CV joint at the time of boot replacement..the remanufactured joints can be had online as cheap as around $50 each...and are equivalent to the OEM part costing 5 times more from a dealership and 10 times more if new. Shop around for replacement costs too. $90 shop labor per joint is the going rate as of Nov 2009 in the DFW area...whereas dealers want as high as $300 each for just labor each joint. Hope this helps..I'm about to go through this myself so did some research first.
