Home-Made Posi Lock?

Hey Guys,

I had to use the 4X4 the other day, and had to wait a while for the light to come on. I was wondering if anybody has attempted to make a home made posi lock out of the existing thermal actuator. The posi lock is too expensive for my budget right now, and I like to do home made jobs. Could this procedure be done? Just something to think about.

Re: Home-Made Posi Lock?

yes it can be easily done i think. if you need any pictures of what the parts are/do, just let me know and I"ll hook you up. i think you could do it with a choke cable, a bit of metal rod or bolt stock, and some various screws bolts and scrap steel/aluminum.

Hang Yea, I would love pictures! I didn't actually think it could be done. Have you done this mod? That would be a lifesaver for me. Thanks a bunch.

Re: Home-Made Posi Lock?

<font face="Comic Sans MS">One way you might be able to rig it up is the S series (some of them, my 85 for example) has a vacuum actuated setup. The part that screws into the differential has a cable coming out of it though. Could find out of the threads are the same and if you could rig the end so you could connect it into the axle, then it's just a matter of hooking, securing or welding a choke cable onto the actuator cable and all set...

I think since I do not have the time to make my own posilock, I'm going to wire the stock thermal actuator to bypass the transfer case selection. Then you can leave that engaged all the time but only lock the case in when you need it. Not a perfect solution but it's better than nothing... [img]images/icons/crazy.gif[/img]</font>

Re: Home-Made Posi Lock?

i have not done this mod. i have put in a posi-lock though. i can goive you all the info you need about it. without the right toolsa nd i na parking lot in january, i installed mine in about 2 hours. it shouldnt take you too long to do. the onlt hard part would be getting the rod/bolt stock to push the "dildo" out. do a search for dildo. i made the original post with it, but a guy by the name of blusmbl i think took a picture of what oit looks like in case you havent seen one oustide of its hole in the diff.

okay i found the pic of it. i packed them in condoms to take up space and save weight as well as keep gearlube off of teh box. heres what it looks like

It's cheesy like usual, but it gets my thoughts across.

Re: Home-Made Posi Lock?

There are mechanical type engagement in S10's front axles too. That cable thing used to cost over $100.

I've got a 4.11 front axle out of a S10 that I've been trying to sell for a year. In fact, I keep tripping over the freaking cable. I can probably pull it apart and see how it works so we can figure out if it will work and then he can go to a junkyard and grab one.

picture of it on the ground:
