Iíve had the Jeep bug for about 5 years now, and I finally got one. A '92 YJ with the 6cyl 5spd. The problem I'm having is when I got it, the previous owner took out the 4X4 vacuum lines because the actuator was no good. So now that I finally got my dream vehicle how do I get the 4x4 back on line so I can play. I really have no clue what I'm doing . Hopefully you Vets can help a newbie out.
It is manually actuated. They are easy to install. When you shift your transfer case into 4wd, you then lock it the front axle with the posi lok. The vacuum motor is controlled by a switch on the transfer case. If the vacuum lines or motor fails...no 4wd. Chevy's use a similar system. Older models had an electric actuator that would heat a gas that would engage the axle. They were also prone to fail.
yeah mine is always locked too with washers. the only thing I notice is the steering is very grabby when turning. as in it almost fights you when trying to steer around a sharp turn but not always and it could be certain roads. it will turn to sharp or not enough and it can be a little tough to take a turn without looking like you are distracted or something.
Is there any long term problems with that? I'm just curious. I know you'd have it shifted into 2wd but having the posilock on will still always engage your front differential and drive shaft correct?
If you front end is balanced right you can get bad vibrations. But it's unlikely. With the posi lock you make the three piece axle a two piece axle. That you can engage and disengage. When you lock it over with washers, it does the same thing but you can't unlock it unless you take off the CAD/vacuum and shift fork housing.
The only advantage to posi lock is 2 wheel drive low.
And no posi lock does not always engage the front axle/differential. It's only engages when you pull the cable and lock it in.
If the cable doesn't strip and leave you stranded in the damn woods, making you rig it to work right. That's what mine did. And I haven't unlocked it since.
If you want my honest advice, from my experience, the posi lock sucks. Just lock it over with washers. Or if you want it to be nice neat and clean, get the permantly lock CAD I think they are 50$
Cole I think you must have done something wrong when installing your posi lock. You're the only person I've ever heard have problems with it. I like mine a lot, and it works great. But locking it permanently works great too. To each his own.

So I ran outta gas today and wouldn't you know the only person to stop was a fellow jeep owner. He was a really knowledgeable jeeper, he told me just locking it in its the cheapest and best way, and he could have it knocked out in half an hour, thanks for all the advice. I really do love being in the jeep community.
