Posi Lock?

[88whitemanche]

Has anyone here tried the posi lock system? I know we have a link here with the cad fiz but wouldnt a locked front axle give more wear and tear and consume more gas? For more drag?

Just about every other jeep or 4x4 made since the mid-80's and '90-newer Comanches abandoned the CAD for a reason... and there seems to be no adverse effect on mileage or wear. The CAD system still allows more parts to move than lock-out hubs anyway. As to the posi-lok: I have seen issues with them off-road in which the cable does not have enough slack and they break/mess up upon flexing. One came with the spare parts I got with the first MJ I bought but after looking into it I craigslisted that bad boy.

that was the theory, yes. turns out the amount of gas and wear is so small as to be unmeasureable and Jeep thankfully ditched the stupid design in the early 90s. :shake:

 

the only thing you'll notice is if you've got a bad front driveshaft ujoint. :thumbsup:

Cool so its not worth the 160$ for posi lock and just do the c~clip fix on the cad

Originally When i got the posi-loc i didn't have a locker up front, so i retained the cad it so i could have 2-low. I now run the Posi-Loc and a Powertrax no Slip up front. I got the longer cable and ran it with best forethought to prevent damage (ran a lot of it through radiator hose for added protection. I enjoy having the Posiloc as I can put in 3 wheel drive low range when launching the boat, it makes it easier to turn once i hit the concrete at the boat ramps. Hind sight I would have removed the cad with an axle from a 92+? and purchased a terra 2-low kit. I would have then felt i needed a select locker up front, however people will say they have no adverse steering issues with an auto locker and having both axles engaged. All manufactures strongly advise against an auto locker up front w/o a disengagement though.

There are how-to's on here where you can take the cad shift fork off, turn it around and re-install. And bam no cost 4x4 with out worry of vacuum cad not working. it will then be just like 92+ maybe a little weaker because of the collar, but no monies, just a little time. Then you can see how it handles before and after and decide if you do want to eliminate it completely with the full conversion (requires new seals so the carrier has to be pulled, new single piece axle, new u joint). the passenger axle can be a junk yard pull so you could save some monies there, but you do have to pull the carrier and replace the seal.
