How hard to strip a front and rear diff? Any special tools needed?
 

How hard is it to strip down an escos front diff and 2wd 7.5" rear diff?

I want to strip them down to blast casings and tap a few threads etc before rebuilds,

A specialist will be building them back up but would be easier if I can strip them down and do the blasting and tapping before he gets them to rebuild.

Thanks
Marc
