Hi Mike,

Isn't the Dana Power-Lok the limited slip setup (clutches)?

This is sounding better and better....I really don't need the big "bangs" from
time to time....I just wonder how often the clutches wear out....

Thanks everyone for all the input....

Ted, that is a brake warning light. Tells when levels are low.

From: Sleddog
Subject: FTE 61-79 - differentials - lockers and torsens

i have had detroit lockers, open diffs, limited slip and torsen gleason
types. i hate open diffs, love the detroit locker and torsen. i have
never destoyed a locker, but all other types i have completely busted. (a
spool is my next step!)

for anyone considering a locker for a street truck - i had no problems on
the street. that occasional loud bang wasn't too bad, and i never heard
those little clicking noises unless the engine was off and i was coasting
or being pushed/pulled. i find that lockers are more consistant in snow,
and therefore easier to drive but an inexperienced driver would most likely
find difficulty staying on the road.

the torsen diff is now marketed under the name zexel-torsen. it is a gear
type with no clutches, but is not a true locker. it gives "soft"
engagement, and turns without noise, jerking, extra tire wear or any of the
"bad" traits of lockers and posi's. it is the best of all possible worlds.
it is designed to allow a certain amount of speed differentiation, but no
more. enough difference to turn, but if one wheel is in the air the
grounded wheel gets power. unlike a locker in this situation, the torsen
will allow the free wheel to turn a small amount faster than the tractive
wheel, but the difference on the trail is not noticeable, and on ice it is
not either.

i had the torsen in my dana 44 front for 2 yrs before i destroyed the
gears, carrier, bearing caps, etc.

i destoyed it from way to much power and hot doggin' it through mud & snow
over rough terrain. i abused it, but under normal or heavy duty service
with milder engines they will hold up no problem and they are the best you
can get IMHO.

other wise, the detroit locker is the only real good choice. ARB is big
$$$ for a product that is good, but i have my doubts about their
reliability after seeing the air system. some poeople have had problems
with the air supply, smashed airlines and such or a leak inside the
housing. but, it could be used to pressurize the housing for underwater
jaunts!!

and a warning for all owners, or potential locker owners - make sure the
rolling radius of the tires on the axle is the same. do not adjust to
equal pressure, adjust pressure to equal out the height of the top of the
rim on each side to be equal. this is pretty important for street use, but
on the trail it makes little difference.

Let me know what you all think of this idea. After

>gathering as well.

Ken,
I think in 20 years or less you will be saying/we all will be
saying, "what have we started!!" This is FTE in its earliest stages of
infancy! Let's bring in the union!
:) This group will do nothing but grow and become a major player in years
to come with
Ford trucks! I see it in my crystal ball. Thanks Ken, be a visionary! I
am honored and proud to be a part!

***** Someone made mention that parking in Pigeon Forge was at a
premium. Help me out here. Where is a good place to park and ride a
shuttle? I don't feel like hoofing it 14 miles from Dollywood.

The Trac Loc and Traction Loc are both clutch types and are
rebuildable. Not sure if the Power Loc is the same as the Trac Loc
or not but the Trac Loc is Dana and Traction Loc is ford. They say
they're good for about 50k miles. The Auburn is supposed to be good
for 100K miles but is not rebuildable. The OEM ford Traction Loc
with 4 spider gears is one of the strongest rear ends around but does
not fully lock except under very heavy loads and with some brake
> applied.

If you are made of money the best all around traction device which
can be used front or rear or both for combination on and off road is
the Torsen gear type limited slip but the last quote I got for this
was $1300 just for the diff.

The one I like is the ARB but is expensive also and prone to little
nagging problems if you don't set it up right and with good materials
etc..

The True Trac is similar to the Torsen in that it's all gears and no
clutches but not as strong as the Torsen but much cheaper. Many put
this one up front and use a locker or Traction Loc in the rear. Some
have said they added some strength to it recently so it may be strong
enough for the rear now, not sure.

Subject: Re: FTE 61-79 - Rear Lockers

Jeff,

Yes, it is.

Its a clutch-driven limited slip, but there are configurations of the
clutch
disks that let you modify them for a more tighter or looser feel.
The replacement clutch packs are available at any dealer who
carries Dana/Spicer parts, or places like Reider Racing. I've ran
them in my jeep for the last 7 years and like them a lot. The one
in the rear of the jeep was just replaced with a used Detroit that
I got for next to nothing. The clutches in the Power-Lok were showing
signs of wear, but this vehicle sees a LOT of off roading here in AZ.
$50 bucks for a new set of clutches and she's brand new again,
and I put it in the front of my Ford pickup. It already has a Power-
Lok in the rear.
The front Power-Lok in the jeep is still pretty tight after 7years-
I don't forsee going back into it anytime soon.

Another thing about the Power-Lok over the
factory Trac-Loc limited slip - the Power-Lok has a 4 gear
design riding against the side gears where the Trac-Lok only has 2.
Power-Lok distributes the stresses much better.

Here's a secret for the Power-Lok. If you're rebuilding one for a front axle
you can "shim" the clutches a little, say 15-30thousands with some
pinion shims or whatever, to tighten the Power-Lok up a bit. You can
actually
make them so tight they act like a spool.:-) You can also shim one for a
rear
axle, but the clutches will wear out a little quicker.

Now everyone is going to tell you the Detroit is the ultimate locker out
there,
and they're right for the most part. The Detroit IS the ultimate for
off-roading,
bar none. And, they're ok on the street, providing you can live with the
clang and bang. But, the Power-Lok is more livable on the street, and very
acceptable off road. Everything is a trade-off of some sort.:-) It just
depends on what your needs/wants are.
They're also right in that you can't hardly break a Detroit ( although I
have
seen them break in abusive conditions) but the strength of the Detroit will
cause the stress to move to the next weakest link, i.e. the driveline,
u-joints,
gears, etc. The Power-Lok has slippage in it by design, and when you get
in a bind or sticky situation they will give a little.

You have to decide for yourself what your needs are and what the purpose is
going
to be for the intended vehicle. I own both a Detroit and Power-Loks and
love them both, in there intended applications.

Hope this helps,

Mike
Phoenix, AZ.
