Rebuilding a Toyota Tacoma Diff Lock is certainly a DIY job.
I took a stab at rebuilding my 2003 Toyota Tacoma’s diff lock 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 Toyota grease used during the rebuild (expensive stuff!!) is part number 08887-02007.
