4x4 Posi-lok?

I've been looking at the posilok systems and have been wondering if it's a good set up to go with. Any advise is welcome thanks in advance!

I've got the 4x4 posiloc system,I bought the jeep used and it had it already installed.
I have no complaints with it,though at first I didnt like the way it engaged by use of the control knob but I got used to it. I think its better than haveing the vacume hose set up.

i just bought a kit and it came in today, it seems REAL easy to install (*knock on wood) I'll let you know how it goes. That vacuum pump system is one of the weak points in the jeep. You can also have 2WD LO, and i think the kit works well with lockers if you go that route.

my 4HI/LO failed about two weeks ago so I'm not gonna mess with the vac system, go straight to cable.

The best thing to do is to just do a by pass.
I have had mine set up this way for a very long time.
it will not effect your mpg, handling, ride or cause any extra wear.
and is fool proof.

I have a posilock in mine and it works fine. You can just lock it like Scott mentioned. As long as the transfer case is in 2H you won't know the difference.

i suppose you could just physically move it into place and leave the tcase on 4HI

this has some pictures, it is the installation instructions for the 4x4 posi lok

yea its great, it takes a little getting used to to operate but once you get the hang of it (about 5 mins of practice) its really easy to use. Basically it can be difficult to get out of 4x4 if you are not moving so you need to be rolling forward about 5mph to 10mph to get it out.

Posiloc

I have had the posiloc system for seven years now. It is better than the stock factory vacuum actuator BUT IT IS NOT AS GOOD AS REPLACING THE ENTIRE SYSTEM WITH THE PROPER EQUIPMENT. Superior Axle and Gear makes a conversion kit for YJ that gets rid of the actuator system. All you have to do is put it in 4WD mode and you are in gear. It is about $100 more than the Posiloc system. It is well worth it. Scott Howard's post is "right on" the money. For the money and safety, the conversion kit is safer and better.

I don't know about you guys, but I have been in situations where the difference between going into 4WD and saving my life was microseconds. I truly believe the automatic 4WD system is better than the Posiloc sytem AND it is much faster.

Jeep had continuous problems with the vacuum system on the YJs. They went back to the old way with the TJs.

Take care,

Take care,
i totally hear you an automatic switch is faster, it takes me about 2 seconds to engage the posilok. I could prolly do it faster if my life depended on it all it is engaging the tcase then pulling the switch.

Posi lok is a system to engage/disengage the front differential into 2wd/4wd via a cable instead of the vacuum actuator the YJ's used originally. It is not a means of locking the diffs like a limited slip or locker differential carrier. That is something else all together.

Cool so it only engages the front for 4wd, I like having my open diffs cause street use they are great around corners

I had the posi lok first but after a few years started having problems with it not staying engaged or not wanting to come out of 4wd. I replaced the passenger side with a TJ shaft. Problem solved for good.
