Drive shaft stuck

Hey tw just looking for some little tips/tricks. I need to change my upper u joint. I was trying to pull my drive shaft, but it would not separate from the diff, yes I obviously took off bolts. I hit it a little with a rubber mallet. Pushed and pulled s little, but it would not go anywhere
Any ideas?

A bigger hammer was the answer here.

 

Auto? Park brake on, in neutral? Prybar and muscle.

 

Ya it's automatic, it was it park not neutral. I did try a pry bar and hammer but no luck. I was hitting it pretty hard I didn't wanna bend or hit something else

 

If all the bolts are off and you can't get it off by hitting it with a hammer. Put the parking brake on start up your truck and put it on drive should break free from there if not rock it between drive and reverse
