Question : Changing a cv half shaft on a Hyundai Sante Fe, 2003, right side. What if anything holds the spline into the transmission? and I have been trying to pry at it it does not seem to be moving any other suggestions? Answer : Nothing. Once you have the shaft loose from the spindle, you can pop it right out. You may want to place a small amount of pressure with a pry bar to pop it loose> ( its been setting in there for a while ). Also, One thing we do in my shop when a cv shaft is stubborn, is to set a block of wood on the backside and hit it with a sledge to pop it loose. Make sure it is already loose from the spindle and free to move. If you look at the new one, you can see how far it need s to come out.
