How much grease in the rear axle?

Is it oozing out the seals somewhere? You should be able to pump it full until there is resistance on the gun, then you stop! or you will make a seal pop out!!
 
Dam the seal came out on the right side! I took the screw out rode it and a bunch just came out. Is the eal ruined?
 
Just took a ride with the fitting in, no leaks but the seal on one side is bulged out. I guess if she blows she blows!
