2004 Tacoma ADD?

My Tacoma has a manual t-case and no locking hubs so I assume it has an ADD. I've had vacuum actuators fail on me in the past without knowing until I got stuck. On my F150, I could replace the actuator with a cable system. This gives a tactile feel so you know its engaged.

Does anyone make anything similar for the Tacoma?

 

^I've never heard of replacing the vacuum actuators with a cable setup on a Tacoma. That being said, I haven't heard people complaining about their ADD setups not working either.

I've got manual hubs though so, what do I know...

 

3 4WD Tacomas (2001, 2005, 2010) all with ADD, and NEVER a problem engaging the front end... about 300,000 miles combined.
