How to: replacing the 4x4 front differential actuator

[OverBoardProject]

Look into heavy equiptment sales and parts. They use cables simular to the posi-lok's for the throttle.

To be perfectly honest I like the idea of the posi lok, and the quality of the cable, but I'm very disapointed in the quality it the rest of it.
If you look the cable housing is about an inch from it's clamp. Well it wasn't like that earlier, and the clamp was as tight as possible.
I got lucky that I didn't need 4wd that day, being in a snow storm in the back country. (it wouldn't have worked) This was the second time that the cable slipped in the cheap clamp.

The good thing though is it's always the same problem, and as long as I have the right Robertson screwdriver (yes that's right, they enclosed a robertson... square screw in the package) and a pair of pliers I can fix it in about 30 seconds.

I've actually taken the time to e-mail 4x4 Posi-Lok today, telling them that I can't recomend their product unless they've improved the quality, and tell me how to cure the problem that I have with mine (I really want them to send me a better quality cable clamp system)
I'm hoping that they respond with a solution, and I'll post any response (good or bad) from them here.

It is really the cheap quality clamps that I have the biggest issue with. If they change it to a quality, good design I would recomend their product.

There is the link to a install sheet.

OBP didnt they give you the cool lock unlock cable dealy that is pictured in their. That i think is what threw me when you said you didn't have the right length cable.

[OverBoardProject]

They gave me the cable, and it should fit in either location.
The cheap hardware allowed the cable housing to slip, rendering it useless.

I might have worded it wrong.

Lol that makes sense to me now.

4x4 Posi Lok has not returned my e-mail, so that tells me that they DO NOT stand behind their products.

I know that I won't buy anything else from them.

Thanks for the heads up . I will look for other ways then . I have had several businesses that have not replyed to mine recently . Rob

Does this posi-lock cable system simply replace the need for the actuator? If its something like the switch on the x-fer case or the encoder motor that isn't working, will this setup still work?

[OverBoardProject]

It replaces the entire vacuum actuator

I'm getting rid of my auto hubs altogether soon, and it might be easy to talk my out of my posi lok.

Just so you know I'm still not happy with their customer service, or a better description is they don't have any customer service. I'll never buy another product from them.
My last post is over 4 months old and I still haven't heard back from them.

I don't think that you'll want to get rid of the auto hubs like I am. It's a lot of work and a lot of money, although it'll be tough. I've got most of the parts on a parts truck, so it's mostly fabrication for me.

I'd really like to get rid of that actuator system. I don't like it very much, especially with my problems with it lately, lol.

I liked the look of the cable system, too bad it has cheap hardware with it. I was interested when I first looked at it until you mentioned that part of it.

How hard do you think it would be to fabricate that type of system?

[OverBoardProject]

Not too hard at all, the cable it's self is the only hard thing to find. A throttle cable from an excavator or some other piece of equiptment would probably work.

I'm probably pulling it next week some time, if you remind me in about a week I'll take more pic's of it.

hi im trying to convert my 1989 chevy blazer from a 4x4 to a RWD if thats not to much trouble please help

[prozac_420]

my last post sayed

"hi im trying to convert my 1989 chevy blazer from a 4x4 to a RWD if thats not to much trouble please help"

and the reson for that is that i want to put air ride suspension in it but i want to no if its just cheaper to buy the 4x4 air ride suspension kit which is 3500 dollers and would converting it to RWD save me money if i do it myself becuz a regular air ride suspension kit would cost aroun 1500 thnks for reading. happy truckin lol

ok i just took off my actuator and it seems to work fine, when i plug the whole on the left side it holds pressure. But my question is was there supposed to be a vacuum line on the side of it?? And if so where is that vacuum line supposed to start? I've looked everywhere and can't find the damn thing.
