I am needing help removing my rear drive shaft. I cant seem to get pin out! Tried putting a drill bit in it and hitting with a hammer and now the bit is stuck. Any ideas?

 

Penetrating fluid. Let it soak in overnight.

 

Had a bike I couldn't get the drive shaft apart. Sprayed it down really good with some PB Blaster and let it set overnight. Next day, one light tap and it fell apart.

 

Got the pin out...now cant get yolk to come off diff. I have soaked it for about 24 hours or more and it's not moving at all. I toke diff off to be able to get to it better but no luck. I thought it just slides right off but my case. Any help here

 

Air hammer is useful. Just try not to damage anything. Probably rusted on. The shock from the hammer cycles can actually break rust free. Have seen it several times. Most people( in my area anyway) went aware there was a zero on there anyway, so the get rusted.

 

We got it finally! We are putting everything back together now the axel nut wont start on spindle. No cross thread at all. No damage that I can see. It will turn once then get tight like it wants to cross thread. Any ideas here?
