Is the e-locker from a 2001 tacoma interchangeable with a 2000 4 runner

I have a 2000 4runner that i want to switch the third member with the e-locker from a 2001 Tacoma, will they work?

 

An elocker diff will not fit a non-elocker housing without modification. The gear ratio also needs to match yours.

Thanks for the info, the gear match i am aware of , what mods to the axle will need to be made?

 

Stud patterns and there is an additional notch in the housing for the E locker. Honestly it's probably easier to swap an entire elocker axle assembly than to retrofit the elocker diff into a non-elocker housing.
