Front diff, locker or limited slip?

Asdf 15 February 2005 19:39:35
 Time to upgrade the front diff. Any stories? What experience
have people had with a full locker in the front differential?

 It depends what vehicle and what purpose...

A front locker makes steering pretty hard and can more or less be only
used when needed on rock climbs and mud ..

A slip is more driveable but will only give you some traction to the
other wheel ..

If going for the locker make sure your axles will hold up to it. if you
have an IFS toyota they will not . I have such truck and use a
TrueTrack in front.

 you could have the best of both worlds with a selectable locker such as an
ARB or OX locker (fully locked when you need them, open when you don't)

I suppose all lockers have this option.
Otherwise the car will be impossible to drive/steer on more solid
ground.
And on tarmac the car will fall apart.....
Kind regards,

No, very few lockers are manual. Most are just on so unless you can
unlock your front hubs, you don't want one in front.

 We have to distingiush between:

- Spool/Welded Diff
- Automatic Locker (not talking about slips here)
- Manual Locker

Listed in the order driveability .

 Reverse order of driveability, that is

Yeah, sure. In that case it is possible.
Was only thinking about air lockers.
Kind regards,

 I belive that the best option for your rig would be to get a locker
that works as a limited slip while not locked.Your front end will last
longer and you have the option of steering if need be and not blowing
your front suspention on one smooth scoop.I have know people who have
either welded or locked the front ends and due to lack of steering they
hit trees rocks and other objects that they could steer away from and
then break steering components.

I had the guy put a True-Trak gear-driven limited slip in my front diff when
he regeared my TJ (Wrangler)... I never even notice it other than a lot more
grab up front when I'm wheeling. OTOH, my Jeep SUCKED on ice up at elk camp
last year but I think that was the MT/R's as much as anything.

Wow! Great input. I have to start asking more questions here.

The truck is a 1971 Chevy K20, manual 4-speed, manual hubs.

I drive to Tahoe a lot so snow/ice is a big concern. I have
heard bad stories about lockers on slippery streets. So the
options seem to be either limited slip on both or something like
OX or Truetrac Electrac. Eaton alos now has an electric locker.
Those lockers are both around a $1,000 though. I was leaning
towards limited slip, but wanted a more aggressive for off road.

what if I put limited slip in back, put a Detroit locker in front
where I can unlock the hubs?

Another thought, if my transfer case is manual, I could even have
the Detroit up front with the hubs locked if I was in 2-hi.

 i agree that that a front locker really dependes on the application.....
in the gooey stuff it rocks, but on the tight trails it bites.
My particular setup is very versatile in that i am running a NP205 transfer
into
a full spool with manual locking hubs.
I can unlock 1 side independent of the other choosing from 2,3 or 4wd.....
pretty slick setup.

In snow/ice circumstances it will even damage the whole car.
Whatever you do.... it will follow a straight line (theorethicaly).
Anyway, it will go wherever it wants to go and you can't do anything
about it.
Kind regards,
Erik-Jan.

I sure will, even a part time 4x4 system can cause that on a turn
because the rear and front axle are locked together so one front tire
has to scuff on a turn. If there is heavy snow/slush down or if you
have wide tires, this scuff can get you up on top so you just go
straight.

When I am in that kind of snow, I drop to 2 WD as I take the corner and
go back to 4x4 once straight again.

 So, front end will either be a limited slip, or one of those
manual lockers I can turn on and off from inside the cab.
I'll put a regular locker in the rear.
