Easy DIY job. Carquest has them for $69/ea and Pepboys for $99/ea. Both offer lifetime warrantys so who cares if they die every few years? My local axle shop wanted $250/ea to rebuild..... Granted I blew an axle immediately after I installed them but I think I overextended the axle when I bolted it in. It was replaced under warranty and I have had no trouble in 12K. I say replace 'em both and move on. RT
