I recommend going to Oreilly's Auto Parts for the CV shaft if you are wanting to go with a stock replacement. For the Grand Prix they are about $80.00 to $90.00 depending on which side. This is for New, not Remanufactured CV shafts made by A1 Cardone. There is a 5.00 core when you buy the new shafts. Remans by A1 Cardone are about $60.00, but there is a $50.00 core charge.
