Manual locking hubs?

Hi,

Did Jeeps (CJ or YJ) ever have manually locking hubs or was that just a Ford
thing?
Also, what year and / or models do not have the shift-on-the-fly four wheel
drive where you have to stop the vehicle to engage it? I don't see that as a
huge issue, but I was just curious....

Thanks,
Dan Hoskin

They stopped the manual hubs with the CJ's in 86. YJ's have a vacuum
slidelock on the axle to latch the front wheels in. TJ's are just on
all the time I believe.

It would have to be really old not to have shift on the fly into 4 high
if that even existed....

All the ones I have heard of are shift on the fly into 4H at any legal
speed. You need to be just crawling to shift into 4 low.

CJs have them. YJs have vacuum operated hubs that some people convert to
manual hubs. All Jeep models can shift into 4WD if the hubs are locked, OR
if they have vacuum assisted locking mechanisms. I leave my CJ's hubs locked
pretty much all of the time, and I can shift into 4WD anytime I want to.

You believe correctly.

Is there any reason not to leave the hubs locked al the time?

3-4 mpg and less wear on parts....

None that I can think of. The front axle will cause some loss of fuel
mileage, and there is a camp that says the gears in the front diff will wear
out sooner if the hubs are locked. These two reasons are good enough to keep
the hubs unlocked for most of your daily driving, but if you specifically
plan of going offroading in 4WD, lock the hubs at home, or lock the hubs at
the gas station when you fill up, and take off.


PS
Keep in mind that models before the CJ did not have locking hubs, and the TJ
hasn't got locking hubs. These models had/have the hubs locked constantly,
just like what you get in the CJ when you manually lock the hubs.

3-4 mpg? I sure didn't pick up 3-4 mpg in my TJ when I installed manual
hubs and started running with unlocked hubs!

You know it is likely a bit less than that come to think of it. When I
lock the hubs it is always bad weather so my driving style is usually
different or more uneven because of wind which could account for a mpg
ot 2, but it is always less on mine with locked hubs.

Hi Mike,
My Bronco handles many times better unlocked! We are supposed to
lock them for a hundred miles ever so often to make sure they
lubricated.
