Homemeade D30 YJ disconnect

Hi all,
I searched for this in the archives, I know I've seen something like what I want to do, but couldn't find it. [img]/wwwthreads_images/icons/frown.gif[/img]

What I want to do is totally get rid of the vacuum disconnect system on my YJ, and rather than get the whole $200 cable system, or even bother rigging up a home job, I don't mind getting out of the jeep to lock in the hubs, so I was thinking of how I can turn the vac disconnect into a manual hub.

Anyone know how this can be done? Take it apart and install a knob on the vacuum motor to pull and push the fork is all I want to do.

Thanks for any ideas,
Pete

You would have to crawl under each time you wanted to lock/unlock the front axle. Basiclly you would be doing the same amount of work as home rigging a cable from the cab and it would work better. Check out a tractor shop. They appearently have similar stuff. Or even go to a wrecker and grab a cable E-brake shifter like from an old Toyota.

Re: Homemeade D30 YJ disconnect

Is that kind of setup as good as locking hubs on each wheel?
(getting out and doing it?)

Is it the whole system on a D30 thats Crap, or is it only the vaccum asspect of the setup?

Re: Homemeade D30 YJ disconnect

The D30 itself is not a bad axle, at least for me. With 4.10s, 33s, a 258 and the wheeling I do it's been fine for over 200,000 miles. Put on the 95+ axle shafts with the bigger ujoints, and find some way to get rid of using engine vacuum to energize 4WD, and it should be a good setup. I don't have a locker up front, so I could just leave the thing engaged all the time, but I don't see the point in having the additional wear and drag of the front end components all the time.

So, my plan is to somehow make a manual "hub" out of the vacuum disconnect. I plan on doing this tomorrow, and totally eliminating the vacuum system. Less stuff means less stuff to go wrong. Getting out and reaching behind the tire to manually engage it is really no big deal.

Thanks for the ideas,
Pete
