Darn stubborn fill bolt

Usually don't buy tools I don't need but with age comes needing to do things easier.2005 4runner rear differential fill was seized and very well stuckhttps://www.amazon.com/Milwaukee-2767-20-Torque-2-Inch-Friction/dp/B077H7JP1D

 

Yep, I did the same with the front differential fill screw. An impact hammer/chisel was the only way. I tried an impact wrench, penetrating oil and time. Nothing worked except for the impact chisel.

 

Yup, first time I did mine I had to run over to my neighbor. I always seem to do that when I get into a bind....

 

Then the second time, ran over put it on the lift. Couldn’t get the front diffs drain plug loose. So we just suctioned it out the fill. Good to go!!!
