So, Mine is locking, unlocking. Found this out the worst possible time, last December in the big wet snow. I am looking to put a full time actuator in it, well not really an actuator, but it's like a plug that will keep the dif live full time. My son put one in an old truck he had, AFAIK, he had no issues with it. I hadn't been able to find what he used anywhere. Maybe someone here can. OR I watched a bunch of YT vids, and one guy made one from his thermos actuator by JB welding a piece of PVC in the end to make it depress the fork or what ever is inside, to keep both axles live. Looking at other video's looks like both the motorized and the thermal's are plastic. So what say ye, doesn't seem to take a lot to depress the inside to make it live. And yes, Money is an object. Thoughts?
