Well, next is to pull the hose to the actuator off and use something like a mityvac to pull a vacuum and see if the actuator is any good.

That's the most probable thing.

Actually it is working. Just not all the time. So I figure I just need a new actuator

What are you doing to test it?
the wheels will have to be turning for it to be able to lock the front axle in.
