CV axle replacement

I have the CV joint or trans axle assembly out and discovered the shaft has slop in it and is the cause of the problem, vibration and knocking when no pressure is put on the shaft either giving the car gas or braking. There is a oil seal there and probably a bearing behind it. The book I have on the car does not show anything on the transmission or dis-assembly. What I was wondering is how to replace this axle. Or possibly a diagram. Thanks
