Locking hubs vs lockers?

So I know for you jeepie techs, it's a silly question, but what's the difference if any? I was told by an ex jeepie that I wouldn't even want to take my jeep mudding without locking hubs, I found some on discount jeep parts, and when I looked on quadratic I only found lockers. Now my jeep is a dd, but I want to inject it with some testosterone and take it off road, but still keep it a dd, which I hear matters with lockers. So if someone could clue me in, or spin me in the right direction to look for the answers? Thanks!

Jeeps don't NEED locking hubs to do anything. Old Cj's did but not a TJ.
Put a locker up front and you'll never know its there on road, in the rear its a different qestion.

What exactly is it they do? I know that in the event you lose traction on one wheel it will free spin, I was told with the locking hubs it would prevent that. So you would recommend a front locker?

Not prevent the freespin, but prevent the isolation of just that one wheel spinning

As EdJones says, TJ's do not need or have the old locking hubs. We do not know what Jeep you have so it is hard to give you the advise you are looking for. You can put a lock right locker in the front if you have the dana 30 and it is a world of difference and it will not be noticeable on the pavement when in 2 wheel drive. It is not recommended to put a locker in the back if you have the dana 35.

First, your front hubs are already "locked", they come that way from the factory. You just can't unlock the type of hub the factory installs. That "ex-jeepie" doesn't know what he was talking about as manual hubs wouldn't affect how well a Jeep would do in mud or any conditions.

So what manual hubs do is allow you to unlock your front hubs which is useful in some conditions like after axle breakage or if you want to disengage an automatic front locker. But as EdJonesJeeper said, you can install an automatic locker upfront and never even know it's there when you're in 2wd so manual hubs aren't needed for that either.

So adding manual hubs in no way improves how well it does offroad, they only allow you to unlock the front wheels from the axle which is only useful in those conditions mentioned.

If one wheel loses traction with out lockers then you are basically going to get stuck. With a locker, the traction will go to the other wheel that has traction and move you along. A Jeep really has only one wheel in the back and one wheel in the front that get traction, unless it is a Rubicon, with an open differential. If you have lockers front and rear, all 4 tires are going to get the traction and power from the drivetrain.

You will notice the locker in the front, not to correct anyone. Not that you can FEEL the difference with one installed but you will hear a lot of scary popping noises, and if you dont know that'll happen it will scare the hell out of you. So be ready for loud noises every once in a while.

This is not really true. I have the Richmond Lock Right locker in the front of my dana 30 and the only thing it does when on the pavement in 2 wheel drive is click going around turns. No popping, and no banging and not scary.

Do you actually have a front lunchbox locker installed in your TJ? The most I've ever heard from Aussies and Lockrites when in 2wd is a bit of clicking while in a turn. My No-Slip front lunchbox locker I had in my last TJ didn't even do that, you literally couldn't tell it was there until you shifted into 4x4.

Tj's use auto locking hubs, a vaccum line engages them when you shift into 4wd. Manual locking hubs do the same thing except there is not vaccum engaging it, you have to do it yourself. Even though it says "auto locking" or "manual locking" hubs neither one is a locker.

No, TJs do not have any form of a locking/unlocking hub, automatic or manual. As already explained above, there is no locking or unlocking mechanism on the TJ, no vacuum anything going anywhere in the entire 4x4 system. Period. The TJ's hubs are always "locked". The TJ's hubs are simply conventional unit-bearing hubs.

The old Wrangler YJ had a vacuum actuated disconnect for the passenger-side axle shaft but not even it had any sort of automatic or manual locking hubs. They had the same type of fixed unit-bearing hub the TJ has. I know of no Jeep that ever even had vacuum actuated hubs. An old Blazer and later a GMC Jimmy I owned had vacuum operated automatic hubs but none of my five Jeep had vacuum operated hubs.

Long story short, front locker for dd, both/rear for trail only. Now onto the next question! Which brand is good:-)

*wavey*


And no I'm not sure of my front axel type, I will find out as soon as get back to my jeep though!

So long as your TJ is not a Rubicon, your front axle is a Dana 30. High-pinion standard rotation Dana 30 if anyone ever asks.

What type of offroading do you do and do you have to contend with icy or snow-covered roads during the winter where you live? And if so, do you need 4wd very much to get around during the winter?

And it's entirely plausible to have front and rear lockers in a daily driver Jeep. My previous DD '97 Wrangler TJ had f/r automatic lockers and my current '04 Rubicon has f/r selectable lockers.

Why do you say that? I've ran Powertrax lunchbox lockers in a Dana 35 for years without issue.

If you avoid hammering the throttle and crawl around off-road you should be fine with a Dana 35. I never once broke an axle. If I were a serious rock crawler or something I wouldn't want a Dana 35 for sure but for moderate wheeling I have no problem running a Dana 35. If I ever snap an axle I'll replace it with a Super 35.

Seems like there's confusion here, folks are interchanging definitions of locking hubs and locking differentials. Different things, I think. Probably me that's confused, as usual. Jerry, your posts #5 and #13 are exactly correct re locking hubs.

Currently I shouldn't have to deal with any snow (I hope) been in NE all my life and navy is moving me to so cal in November. As for what kind of off roading? Until November alot of woods, after mostly desert play, don't plan on rock crawling (father in law has heavily lifted 85 cj cj for that) I plan to throw a 2 inch suspension with a winch and 31's on this one

If you're getting stationed in SoCal, don't discount Big Bear. If you go there in the winter (and I HIGHLY suggest it. Big Bear has some awesome wheeling/skiing/snowboarding opportunities), you'll want/need 4-wheel drive in the snow. If you're into boarding/skiing, check out Snow Summit on Big Bear Mountain.

Haha I can wait. Been a skier for a while, and was hoping to use 4wh in the snow, would be nice to be one of those jeeps playing the the 4ft deep median instea of traffic

You've simply been very lucky. No experienced Jeeper would ever recommend a locker be installed into a stock Dana 35c. Your stock locked rear Dana 35c axle is, really, living on borrowed time.

Before I learned enough about Dana 35c axles to realize that it is impossible to "take it easy" on it and not eventually break anything once locked, I installed a locker into it when it had 33" tires on it. It withstood one VERY careful/gentle offroad trip since I wanted to be careful with it, but several weeks later it grenaded while doing a very gentle u-turn on the street at a light-controlled intersection.

Where a stock Dana 35c axle with a locker installed is concerned, it's only a matter of time until something like an axle shaft will fail. Especially when running something as big as a 33" or bigger tire.

Check out this webpage... Another broken Jeep Dana 35c Rear-End.

Yeah, I get what you're saying. My experience has been totally different but I get it. I've wheeled with more friends with locked Dana 35 than Dana 44 and I've not seen any problems with my friends rigs. I have seen broken Dana 35s on the trail and I've seen broken 44s. But yeah, the 35 is weak for anything over moderate stuff and the D44 is better... But the 44 isn't perfect either.

It happens... I guess if you're really worried about it get a 8.8. . As for me, I'll keep running my 35 until something happens. If/when it grenades I'll toss a super 35 in and keep on wheeling.
