rear diff fill bolt striped

the rear fill bolt on my 2003 prerunner diff stripped and is stuck in the diff any ideas to remove bolt.

 

My front diff fill bolt is in the same condition

One way is to weld a nut onto it. Then back it out that way.

 

bolt just spins in the diff wont come out.

 

Is the diff still full of oil? It would suck pretty bad if all the oil was drained

 

full but cant check and will need changed.

 

This happened to me and I hammered a socket that was 1 size smaller onto the fill plug and it came right out.

 

Weld a nut to it, thread a bolt into the nut, pull on bolt while backing it out.
