    Ran into this video recently which shows not just repairing the 4WD actuator after dirt intrusion, but also goes over using hose clamps (and a relocate) to prevent an otherwise costly and common problem from occurring.

    He discusses what to do to prevent the problem at 11:45 (video link is timestamped):

    Some searching netted me no results here for people performing the same fix - just a lot of threads about people experiencing the failure and having to fix it afterwards.

    It surprised me that this problem doesn't have a pinned guide akin to the "AC Drain Fix", given the "AC Drain Fix" is mostly a meme while this appears to be more of a real problem warranting a couple of hours with hoseclamps.

    Given how long the 3rd gen has been out, is this an oversight by the TacomaWorld community or a non-issue?

    ---

    For those not able to watch the video:

    The fix itself involves adding a few hose clamps or zip ties along the two breather hoses coming from the transfer case, where the hard line converts to soft and back again (presumably to allow for flex). I will probably perform them, as I can't see why you wouldn't. They then also extend the breather terminations, which come to about the same height as the top of the front wheel well.

    This is just one guy's video, and one take on how the dirt/water gets into the actuator; I'd be curious if others solved it a different way or see a flaw in the solution. I am tempted to say he is wrong, and that the intrusion is coming in solely from the breather intakes; it's clear from his video that mud and water have splashed around the breather intakes. However, its pretty cheap and easy to solve for both ingresses.

    I guess I should ask a better opening question - has anyone had a premature actuator failure that might've benefitted from the preventative work described (clamps to help keep diff/actuator breather sealed)?
