I am new to Jeeps, Ive been thinking of something and need insight. If I have
this correctly, my Wranglers hubs are locked full time, contributing to lower
gas mileage, wear tear, drag... Does DC or us only use these for convence or
strengh?? Why wouldnt we use manual locking hubs, except for the getting out
to lock them they seem like a better deal. More mpgs less wear, drag and such.
I had a 88k5 a long while ago with auto locking hubs, you just had to stop and
back up to get them unlockedafter shifting out of 4. I could imagine strength
issuse with those though.
Any insights to educate me.
thanks
Tony

 

Seems like having manual hubs would be better as well if you had a full time
locker up front too.

 

Hi Tony,
I think the key word with Chrysler Daimler is cheap.
Buy a Warn like Real Jeeps use:

Depends on what year of Wrangler you have. The '87 to '95 Do not
spin the differential. (Admitedly, they do spin the knuckle
u-joints) And for those of us who like to be able to drive down
the road in the winter and pull it into 4wd in the comfort of a
warm cab, I can get used to it.

Manual hubs were used in the dark days when bearings, differentials, and
transfer cases caused enough drag that Mr. Warn had a ready market for his
manual hubs when he invented them. Since the introduction of unit-bearing
hubs and better drivetrain components and bearings, manual hubs really
aren't needed any more. And even with a front automatic locker, a manual
hub is still not needed since you can't feel the locker's presence when
you're in 2wd, at least not in a TJ.

I have a TJ and recently installed Warn manual hubs to get Warn's stronger
4340 axle shafts after breaking an axle shaft on Sledgehammer in Johnson
Valley a few months ago. I literally can't tell any difference in how it
drives now and how it drove before I installed the manual hubs. I have also
had a "full-time" Powertrax automatic locker in my front axle for about two
years now so it was there before and after the manual hubs were installed...
there's literally no difference in feel whatsoever.

Roy, the YJ's driver's side axle is connected all the time so it does spin
the differential. Only the passenger-side is disconnected when in 2wd so
the YJ will steer better when in 2wd.

Does the YJ's driver side axle spin the differential, or just the side gears
and spider gears, causing the passenger side half axle to spin in the other
direction?

Correct. But the left wheel just spins the spider gears so the
ring, pinion, and driveshaft do not turn in 2wd. Much less wear
and tear than reverse driving a high ratio ring and pinion.

Now, for another exciting journey through the History of Locking Hubs ...

Early Jeeps had full time hubs, hubs that could not be unlocked. The trouble
was that the technology of the metal was not very advanced, and the parts
suffered from excessive wear because gears were turning that weren't being
used for anything. Along came the manual hubs that the driver/participant
passenger could get out and lock in when needed, and unlock when not needed.
This gave longer life to the gears and other parts as compared to the
previous iterations. Eventually, the manual locking devices were replaced by
vacuum activated systems, allowing the driver and participating passengers
to remain seated. There were marketing advantages here as well because many
4WD makers had actually improved the metals used in the axles and transfer
cases, so having systems where your customers had to get out to fiddle with
***** and dials was a severe disadvantage for sales quotas.

Today, we have significant advances in metal technology, so we can do away
with locking hubs altogether. No manual hubs, no automatic hubs, just plain
old hubs that are always mechanically connected to the rest of the
drivetrain.

The wear and tear, and lower fuel mileage are insignificant, and the only
reason to use manual hubs is so that if the ujoint(s) break, you can
separate the broken hub from everything else, and limp home in 2WD.
