Help with rear axel...

[///MBaller]

My right rear axel keeps popping out. it doesnt totally pop out but it loosens from where it connects to the differential. Could it be bent and thats the reason it keeps coming out. My diff was leaking one day so i put it on the lift and i found out that the right rear axel was loose and i was able to pull it out with my hand. so i popped it back in and it stopped leaking for a couple days, and now i checked again and its loose again. can anybody help me out here? thanks alot

Well, it looks like there's a problem if you can pull it out with your hand, putting it back using your hands isn't going to fix it for sure, you probably shouldn't drive it until you figure out what the problem is.
