Converting to locking hubs

I have a 90 and was wondering if anyone has converted there stock axles to locking hubs instead of the cheeeezy vacuum thing? That thing just doesnt seem very good to me? I would rather get out and lock my own hubs then at least you know you are really locked in? Just wondering if it can be doen or not

Only two real choices, swap axles, or buy a Warn kit. The axle is harder work and lower $$, the Warn is easy work and high $$$$.

i have heard that milemarker also makes a kit that is a little cheaper than the warn, but still high dollar, you could also look into the posi-lok, its a cheaper solution

Is your vacuum engagment working or not?

If you make this mod it will cost you and you'll be kicking yourself in a few months.

I had locking hubs...on a Nissan pickup. And let me tell you, once you have an auto-lock system, you'll never want to be without it again. The thing is, you might never know that you're going to need 4wd as you start out...but then it's raining...or there's a muddy mess on the highway...or you need to get around a blocked road by driving on a slippery shoulder...I could go on and on.

Locking hubs are better than a permanently-twirling driveline, like in the TJ. But they're nowhere NEAR as good as an auto-system, or the cable-manual disconnect that can be used to replace it, that can be worked from the driver's seat.

Sounds like you are trying to fix a problem you don't have, since you did not say you were having any trouble. My 'cheezy' system has worked perfectly since I got my Jeep in '96. It's like any other system in the Jeep, keep it in good order and it will provide good service.

Having the hubs locked in is the same as driving a TJ...if you even remotely think you'll need 4wd, lock them in. When you are highway cruising, take them out. The warn kit is $1000 You can buy a set of d44's and build them up pretty easily for that. You could get a shop to install a front 44 for that.

what moves up and down? the vac motor? the shifter? the housing? nothing should be moving up and down.

The part that is hooked to the axle(lil'' round deal with hoses coming out) It has a gaurd on the back but if you reach down threw the hood and grab the (vac motor i guess) you can lift it up and down. It is staying hooked to the axle it just moves forward and back like toward the front and back i guess you would say?????Why yours dont move???? It seems like it is suposed to???????????????????????????????????????????????? ?????????????????????????

been a while since i had the vac motor, but i'm pretty sure everything was solid. what your describing sounds like the vac motor. there should be 4 bolts holding it to the axle in a rectangular pattern. make sure everything is tight because if it's not, dirt and crap can get into your axle!

Nothing there is supposed to move. I would pull the 4 bolts, clean the mating surface, add some silly cone seal, and put it all back together clean and solid.

Where the four bolts meet the axle housing is not where it moves the little round thing next to that moves! The part that has the lines going to it!!
