Autohub blues

I am having issues with the auto hubs. I have checked for vacuum leaks at the hubs and did not detect any. What seems to be happening is that the hubs half engage while I am driving and not in 4x4. They also go in and out when the 4x4 is on. Can this be an issue with the solenoid that switches the vacuum on them on and off? Is it worth replacing or should I just bypass it and lock em manually? What's the proper way to bypass it? I just plugged the line going to that solenoid for now.

It was obvious to me at the time that they were getting vacuum buy maybe not enough to fully engage so I have just bypassed the vacuum to them. I'll just lock em if I need em. My ac is also working better and not half defaulting to the defrost.

That's the same one giving me problems. Have u taken it appart and serviced it? I was thinking of doing that since the passenger side feels smoother when I lock and unlock it.

My hubs where supposedly just replaced this summer by Ford. Checked out the heater controls thing and where i disconnected the vacuum lines was from the solenoid on the right fender. Still the drivers hub is engaing partially by itself. Mostly when i hit bumps. I was thinking of doing away with them all together and doing the dyna trac conversion kit to the serviceable bearing and spindles; but the old lady likes not having to get her *** out of the truck when its cold to lock the hubs. HAHA
Thanks for the help if anyone else has suggestions I would love to hear them. Cause i'm welling try anything at this point, Short of a conversion thats is.

Sometimes, just a good cleaning and relubing will fix those things.
