GM front axle actuators!

So I have been looking around about these silly little actuators for my 88 chevy axle! There not all that complex of a unit and only have a life span of about six months where its cold.
The question I would like to ask hear is Has anyone made theres into a manual lock out? I know theres kits you can buy so you can put money into someone else's pocket,,, But I would rather keep the cash in my pocket.

Has Anyone ever made this happen yet? I was thinking may be a power door lock machanism or somthing in that line. Anyone elce have an idea,,,,,,?
Things that make you hummmm,,,,,,,,.

just take apart the actuator and use like a shift cable or somethin to get the motion needed to lock in the axles

there is a company that makes a cable conversion, but I cant remember the name. being that yours is an 88 it has the heated oil actuator, you can upgrade to the eletric solinoid(sp) thru the chevy dealer, they sell the solinoid and a small harness to convert. the solinoid lasts a long time.

It's http://www.4x4posi-lok.com/
But the kit is made for stock trucks. If you have any lift you will have to extend the cable. Other then that you can get the upgrade actuator from the dealer that is electric.

Spent,,,,,,,

Yeah,,, I seen the 4x4 Posi units, I found them after I got to thinking,,, Theres got to be a better way. I'm a CHEAP S.O.B. And when it comes down to spending money,,, Well,,, You get my drift. And especilly when it comes down to somthing I can make myself. I already have $300.00 Bucks worth of these Silly little actuators lying around that don't work,,,, and have no value at the scrap yard.
I haven't looked into it real close yet but I think I can make one up with stuff lying arond the shop. Then I will still have that 100 Bucks for somthing I don't want to build,,,, Like Beer,,,,,,

WHAT??.......Beer is "too" easy to home brew. Plus you can play with your brews to alter the alcohol %.....

The plus side to the manual activation is you can have 2wd low as well....if needed to get a heavy load up a steep incline that's paved with out binding up the Tcase.....boat ramps...etc.

Yup, made my own for about $50. Locking push-pull cable from Oreilly/Napa, made a bracket and bellcrank, drilled out the stock actuator and ran a rod through the center with a clevis to the bellcrank.
Sorry no pics. This was 6 years ago, and I don't have the truck anymore.

Looks pretty good, similar to what I did, except I copied the 4x4posilok design and ran the bellcrank off the axle tube.
