Anybody know if the front axle on a '00 S10 can be locked in the engaged position?

My daily beater at work is a 2000 S10 Blazer 4x4 and I need the 4x4. Kentucky's ground is powder when it's dry and slick as snot greasy mud when it's wet. There isn't much of a transition either.

The problem is being a government vehicle the powers that be have decided they aren't going to put any more money into it and the front axle actuator is dead. This leaves me with a crappy 2wd truck on street tires sliding around in ruts, on hills, and wet grass. Thing doesn't even have the Gov-Bomb in the rear.:doah:

Is there a cheap/easy/free way to lock the front axle in? The transfer case works fine, just nothing ever happens up front when you put it in 4x4. The gov vehicle mechanics said they diagnosed it as the actuator when it first went out, just have never been allowed to fix it.
I don't drive it all that far or fast, just around the facility and a few surface streets going to other parts of it. Thing gets like 10mpg because it never warms up, having the front diff always spinning isn't going to make it any worse or last any longer.
 
Bueller?


So guess what happened today at work?

there is a way to fix it using a pair of vise grips.. remember reading about on s10extremist.org or there is that posi-lock 4x4 cable kit, that is about a 200 bucks.. I have one sitting in storage but i am currently in iraq..

Thanks. Someone over on that site said the same thing. Going to do the vice grip method as it's not mine and I can guarantee they won't dump the change for the Posi-Lok if they won't pay for the factory part.

I was told the actuator is under the battery. Going to take a look soon. Been busy at work so haven't had time for this.
 
This may be old news, but I had the same problem on my 1993 Jimmy.

Vac actuator under battery not getting vacuum when 4wd engaged.
Transfer case was switching, but front hubs weren't.

I took battery out and battery tray to diagnose the vacuum problem.
I put the battery and tray back in and rant he vac hose off the intake. It gave me front hubs engaged as long as the engine was running, which wasn't ideal, but gave me 4wd for the past couple days of snow that we had. I have since disconnected it, and will have to fix it correctly later.

The root of the problem as I can see is this. The tranny is leaking into the transfer case and it is flooded. There is a vacuum switch and hose on the transfer case that needs cleaned once I change the rear tranny seal.

Now that I know what the actuator under the battery looks like, it is possible to reach in through the under side and squeeze the actuator and clamp the vise grips on the cable to keep it engaged like the others where saying.
 
I need to get a smaller pair of vice grips and fix this again. I've pretty much abandoned it at work. Drive a HMMWV around instead. Doesn't get stuck but no radio and the heat is meh.
 
It is more than likely just the switch on the transfer case. It cost about $20 and you can find it in the help section at autozone or advanced. Takes less than 30 mins to switch out or it could just be a bad vac. line at the acuator under the battery.
 
It's a government owned POS. Not putting anything more than $2 into it. Besides, right now it'd be the stuckmobile so I'm pimpin' the Mintvee.
