Iinteresting...

The way to get the autolocking hub to lock is to back up several feet then drive forward.  Repeating the process unlocks them.   One would think, because of that, the hubs are "sided".  I don't really know for sure.  I guess the best way to test it is to drive onto loose ground - sand or a gravel road - back up to set the hubs then - with someone looking on - peel out.  If it appears that the front wheels are being driven (they throw rocks) then you got it right.

I DO know that autolocking hubs are not of much use while offroading.  Because offroading often involves backing up to make turns or prepare for a line of travel, you often end up accidently unlocking one or both hubs at an inopportune time.

Hope this helps!

I ran auto hubs for years on my older tracker with 33s, never had a problem.  only time they unlocked for me was when the tire was in the air and I was trying to rock toe truck to get it moving. 


the manuals on the truck were seized solid, had to use a bf wisegrip to get them moving, bent the tabs on the bacm.  the insides were full of rust, I got the one to come apart but the drivers side is solid.  sheared 3 bolts trying to take it off, probably going to replace the whole steering knouckle, I think i hear a bad bearing anyways.

why dont you just go with some superwinch locking hubs?   they have some sort of self internal lubrication system and are pretty much bullet proof.  They've done me good for 2 yrs now..

lol, that'd be nice if they made aftermarket auto locking hubs.  Maybe one that could be turned on by an in-cab toggle swith.  Now that'd be something to invent...

Changing them out is as simple as removing and reinstalling the bolts. If your using stock hubs you'll need the cone washers under the bolts. I've been using Warn Premium manual locking hubs for a couple years now without a problem. Clean and lube once in a while and there great. I also locktite the mounting bolts. BTW, what happens if you can't back up and you need to lock your hubs? Yesterday I was out in the woods and encountered some DEEP soft suger sand, I was in two wheel drive, I locked my rear diff, and proceeded to stop dead in my tracks, even with a locked rear. Couldn't move forward or BACKWARD. Got out, locked them in, dropped it in 4w, and drove right out. Try that with auto hubs.

The Suzuki Jimny has vacuum operated hubs linked to the 4wd switch.

If i remember correctly, when i pulled the auto hubs off mine, there was some kind of locating washer or locating tab between the hub and the shaft or somewhere in there.  This is what would tell the auto hub if the shaft was moving or not (I think) and then the hub would engage if necessary.

When i put the manual hubs on, i noticed they don't have that, yet it slipped on as a direct replacement no problem.

I have a feeling that you can't put an auto hub on in place of a manual hub due to that tab.  I'll see if i can get a pic of the auto hub i took off.

you dont need to back up with auto hubs to lock them.  just throw in 4wd and carry on.  you only back up it 2wd to disconnect them

The reason i replaced my auto's was because when i backed up in 4wd low or hi, or 2wd, they would disengage.  They were "worn out" i guess.  I'd never want to use them again.
