advice in breaking apart the front outer CV joint

I did both of my front outers several years ago now. These square  
wire circlips are a real PITA compared to the round wire clips that  
are just forced into the shaft groove and off.

Using the axle bolt as a pusher, clamp a vice grip on the shaft  
spline to use in offseting the bolt torque. Sounds like you may have  
the square wire section of the circlip pinched between its shaft  
groove and the CV housing from your beating it with hammer. Drive the  
CV back on the shaft a little to where the clip is free to spin. Now,  
holding the clip wide open, you should be able to screw in the axle  
bolt and force the joint to move outward. After it moves a 1/16” you  
no longer need to hold the clip open as it will be up, out of its  
groove. When you run out of bolt length, add a short length of rod  
under the bolt  to force the joint all the way off.
