Last time I got stuck and a GM had to pull me out, both rears were slingin' mud and grass all up under the truck. Packed it real good in the bumper too. That was my '03 Cummins powered Ram. Haven't had the pleasure with this one yet but it also has LSD. I remember the chattering clutches of my '95, '98 and '01.5 Dodge Cummins. I still miss the '01.5...

 

They didnt intend so, but i do. Pulling a snowmobile trailer maybe 3000lbs uphill in 2 feet of fresh snow can be tough sometimes...

 

Every limited slip or posi requires some type of brake modulation at some point. These Anti-Spin diffs are of the Torsen design used in military humvees, but the bias is set lower for better streetability. They are not garbage, but may take some getting use to. They do not have any clutch packs to wear out or slip, and once hooked up will work like a locker.

 

I would have to say that these rear ends are not junk but need a little bit to get used to. I went down to a local fair to enter the truck pull and got stuck in the parking lot and only had two tires spinning and was very upset therefore I missed the truck pull. Where my 02.5 truck had no problems in situations like this but I still like my 04.5 a lot more.

As for in other situations it has worked great when I have hooked bumper to bumper with a few other of my buddies ford and chevy's and the anti spin worked great while I was pulling them backwards down the road

thats a small burnout vid from today. Video starts with the tires spinning about 20mph, then i let off the brake and you can hear them squeal until about 45mph. Thats on level one as well. on level 3 it will spin them to about 55mph. You can kinda see a little smoke in the mirror. i only did it for about 15 seconds. Next week ill take one where you cant even see the guy behind me there is so much smoke.

 

here is a detailed explanation

 

we do have wearable components in our LSD diff's the 6 brake shoes that are behind the 6 pinion gears can wear...

our diff is not setup like the one in the pic in the link


i did a quick screen grab of the internals of out 11.5" rear trac rite diff...


i posted it in my members photo gallery, but the image is still waiting for approval [whatever that is for?] so once it is approved, the image will be there [taken from the 2003 service manual for those that don't have it]

edited to add image

 

well I thought these rears with the limited slip were junk and they are.
took the truck in for the posi not working and the 20m.p.h howl and they tell me I need a new rear!! they say the carrier is broken inside. well I'll see how it goes.
i'll let you know the results. by the way the truck has 12k on it.

I guess if one person, out of thousands, has a problem, it just proves that they are ALL junk.

i've had to call my pop to get me out of a ditch once last winter.. there was no way i could have got out solo though... i had 1 rear wheel off the ground [drivers side] and the ditch was a good 2-2.5 feet deep [darn snow plow with extension blade graded the ditch flush with the road surface and i needed to park off to the side ] mudflap bent and pride dented

 

I haven't had the opportunity to try the braking routine, but will the next time I start to slip. Someone said that technique was in the manual but I don't remember seeing it.

If these things have Torsen differentials, as it looks from a picture that is posted in this thread, those are supposed to be about the best anti-spin differentials available. I thought they went away when the switch was made to American axles, though.

I see Nissan and GMC are offering locking differentials. Not that I'm going to get a new truck any time soon, but it would be nice if Dodge would offer one, too.

 

well, i got a chance to try out the diff on the ice on my driveway. about 3 inches of packed and iced over snow. backing up and rear wheels broke loose(only one spinning). decided to try out the dif so I pushed down on the emergency brake one click. Supprise, both wheels started to spin. Didn't get me out but the diffs do work if you use them as they are designed to be used. Complaning that they dont work when you havent used them properly is like crying the 4wd didn't help you from getting stuck when YOU didn't engage it!

 

if your tires leaked air and went flat but all you had to do was put air back in them would that be ok. no ! you would expect them to hold air. i have a anti spin and I expect it to work without me using a e-brake.
out of the 3 Dodge diesel trucks if have owned with Dana rears, these AAM rears don't hold a candle to them.

 

I recall reading an account of one Dodge diesel owner who pulled out several National Guardsmen in their Humvees during a snowstorm, and then showed them how to use the brake to engage the Torsen diff. The Humvee uses a high bias Torsen, but it still needs some brake to engage it in some situations. Tire traction of course is still different than number of driven wheels or type of differential.
