As long as the sub axle on the outside and the transmission flange on the inside are not moving, then that is normal play
for old worn CV joints.
Keep in mind that the axles have to be able to extend & contract during suspension level changes (as the suspension
travels up and down).
I recorded a video of axle shaft "free play" from a Vanagon just now. Will upload later tonight so you can see / compare
to your Bug.
New joints are stiff and will not move easily side to side.
