This sounds like a YJ Jeep issue, I eliminated the vacuum actuator by installing a heavy duty choke style manual cable attached to the vacuum actuator arm, that way I can lock the front diff when I wanted. Make sure you cap off the vacuum line, otherwise your engine will run poorly.

Where is the front differential actuator on a 1998 blazer?
The vacuum actuator is either in the fender or under the battery. The actually diff actuator is on the back/bottom of the front diff. Mine (2000 blazer) is under the battery. It sucks to get to. If you check the actuator and it doesn't move at all, check the vacuum, if it's not getting vacuum, check the switch on the top driver's side of the transfer case. It sends vacuum to the actuator. It has three vacuum hoses coming off of it. It costs fifteen dollars at autozone and usually greatly improves the performance of the acuator.
Where is the 4WD vacuum switch located on the 2002 trailblazer?

Why is your four wheel drive not working in your 1985 Toyota pickup?
Differentials were locked by vacuum pressure on a actuator on the front axle, if there is a problem with this actuator or with your vacuum system the front axle will not engage. You may want to remove the acy=tuator and clean it out, ot locate the vacuum leak in your system.

Where is vacuum for 1989 jeep yj transfercase coming from?
the vacuum valve on the transfer case takes engine vacuum, and uses it to engage the central axle disconnect on the front axle when the case is shifted into 4wd. this is also the cause of the slight delay between shifting in/out of 4wd, and the 4wd indicator light turning on/off - real world, on an older Jeep, it takes up to a few seconds, sometimes, for the engine to pull enough vacuum to shift the front axle actuator. Both the vacuum switch, and the vacuum actuator on the axle are common failures, and there are a number of kits on the market to convert the front axle to use a cable actuator
How do you test the actuator?
If it's vacuum (has hose) just apply vacuum.
Why would your 1986 jeep just stop locking in the front hubs?
vacuum actuator is bad, there could be a hose that is missing, the hose might be weathered and cracked or cut, vacuum actuator might be all gummed up and crappy lookin on the inside, a simple cleaning might work, other then that a new actuator might be a need, not hard to install though
Where is the transfer case switch on a 1997 dodge 4x4?
