Front axle swap

How hard would it be to swap out the front axle on my yj for a axle with lock out hubs. I want to get rid of the posi lock and just do lockout hubs. Are they any axles that just bolt right in place

As far as I know the only axle that will bolt in is out of another yj. Nothing else has the correct spring perches or shock mounts. So some modification will be needed on anything other than a yj axle. Plus it needs to be drivers side drop.

Sounds about right

What is it that you don't like about the posi lock that you feel the locking hubs will correct or provide?

I plan on doing the posi lock over the summer to get away from the failure prone CAD. But if you really don't like it (posi lock), you could always pick up TJ axle shafts..

I just like the lock out hubs and I figured if I could do a bolt and play stronger axle with lock out hubs that would be nice. With my posi lok the front driveshaft still turns while driving. So I guess I just need to adjust it somehow

You can do it but you also will either need to change the entire rear axle or buy new axles with bolt patterns to match the front. CJ axles would be your best bet. So you would need both axles, new spring/shock mounts, 4 new wheels, etc. the best bet to eliminate the CAD is to just put a TJ right shaft in it. If you're thinking of gas mileage it's not noticeable. I have a 92 YJ 2.5j my buddy has an 01 TJ 2.5l I get about 1mpg better. I'm guessing due to the 5spd over his auto.

It sounds like you have PERMA-lock. Or some homemade version of it. POSI-lock is selectable. You can engage or disengage the disconnect. Can you explain your set up? Maybe we can help

It's got what looks like a throttle cable you push in the red button and pull out and then do the same to disengage but you push in and then turn clock wise to lock it but it doesn't ever go flush with the dash so I think it doesn't disengage completely and that's why my front driveshaft still spins

That's the same thing I have. Mine doesn't go completely flush when disengaging either, it sticks out about 1/8" or so. But my front driveshaft doesn't always spin like yours.

Has your posi lock ever worked correctly?

You need to "disengage" it on the dash end, then pull the CAD cover off to see where your fork has the collar aligned on the axle. Once you do that, you may be able to see about adding a different spring or some type of shim inside the fork retaining housing.

I have had a 1 piece axle shaft set up for a long time now and it DOES make the front DS spin, not too noticeable on the mileage vs the 3.07 gearing and 35" tires.... Lol

I don't think it'll change gas milage really and that's not a big concern I just want it to stop spinning so things don't wear out as fast

And I bought the jeep with it on there. Can I loosen the threads going into the cover or something to adjust it

Sounds to me like you need to screw the cable deeper into the housing on the CAD.

I put the Posi Lock on mine a couple years ago, and it took me about 4 tries to get it adjusted properly.

You have to take the housing off the axle, and spin the housing while holding the cable with the wrench.
