I took a stab at rebuilding my 2003 Toyota Tacoma’s locking differential motor (e-locker for short). I’m glad I did, because these units are expensive to replace and the rebuild was fairly straight forward. Believe it or not, the mechanism actually worked afterwards! Be sure to check out the video I made of the procedure:
Below is an image gallery of the rebuild.
The e-locker rebuild kit can be purchased here: http://absolute-wits-end.com/toyota-e-locker-rebuild-kit-8in-diff/
The Toyota grease used during the rebuild (expensive stuff!!) is part number 08887-02007.
