for those of u who are interested. dont waste ur money on the so called posi- unit. my son has an 04 ctd. 26k it has never worked. it is totally useless. i would personally wait till something is available after market. spit under one wheel on a hill one may as well forget moving. unless someone has an answer that we are missing it is the most useless piece of junk i have ever seen come out of detroit. i have been in the business for over 40 yrs. i am willing to listen to any solutions.

 

Posi, I'm not 100% sure but I don't think Detroit makes the limited slip in the 03 and up American Axle Posi's??? They are gear types which will last longer than the cone or clutch types but is still only a limited slip. I do like the GMs with the locker, but it will only engauge at slow speed. They do have a locker that's avalible in the 10.5 ring size, but not our 11.5's. They also only engineer these things for "everyday drivers" not off roaders. While it's not comparible to a ARB air locker, it's also better than an open rear. Mine will always spin posi, if not a little pressure on the brakes will do. Even the same way with hummers, that's how they train you.

 

I've never had any trouble out of mine. It will spin both tires immediately anytime it spins.

 

i have tried everything i know. the brake didnt work, mashing the loud peddle doesnt work. tag says it is limited slip? i think with equal weights either of my trucks will drag it backwards uphill. for the first time in my life i am totally disgusted with something in a dodge.

 

Mine work ok on wet grass and gravel.

 

60000 trouble free miles out of mine so far....

 

put one wheel in wet grass one wheel on dry pavement on a 5% grade then tell me it works. if so i will change my opinion. i have been a chry. fan since 1962 just hunting answers.

 

Limited Slip You can and will break a limited slip loose if you put one on ice, one on pavement and mash the gas (Diesel fuel sorry guys). There designed to help equil the difference in torque between the two wheels helping them spin. Limited slip works off of input torque, Lockers off of wheel slip. So yes you can break them loose.

Unless something is wrong with the truck or it was mis tagged or something it should work fine. Others i think are used to lockers and no, there not lockers. However if you want to make it tighter, machine some new gears (6) make them about .020 thousands bigger and it will act like a spool. Problem then will be scuffing tires and binding in the drive train, but it will lock them together.

Give that a try, see if it helps. Should make it work great.

 

I believe you have that backwards. If a locker worked off of wheel spin then they would all blow apart at nothing because they have no way to slip. They have teeth instead of clutches. Lockers stay locked in when driving straight and ratchet when turning. Limited slips have clutches that engage when a spinning tire reaches a certain rpm.

 

my 90 has a unit with clutches. i won a 100 dollar bet in my driveway. one wheel in wet grass the other one dry pavement. smoked the dry pavement tire. my 82 has the old cone type in a 9.25 dodge rear it will do the same. thanks for all the replys. maybe there is something mechanically wrong with the 04.

 

Well they both work off of input torque really, it's just how. A posi normally helps even out the torque to each wheel. If you put more torque in that the posi can take then yes you'll break a wheel loose

Locker if a wheel is in the air, the torque causes the pin to move forward forcing both "locks" to engauge the wheel. So if there's a load on the wheel, that wheel gets locked up, where with most posi's, that's the one that would not spin (less resistance does) no means a great description but similiar in function.

If your sons slip isn't working there's something wrong. I loved the cone and clutch designs, but even they need to be rebuilt every 50k or so. (depends on how you take care of them) And then clutch's you can rebuild, the cones you can't once they wear out the metal.

There working on stuff for our trucks, there still fairly new, they will have aftermarket lockers and posis for them. I really like the one that AM makes for the 10.5, limited slip, but you can lock it, that's sweet.

 

Mine works great, especially with the stock Michelins that will get you stuck on wet grass. Do have to use the brake sometimes to help get the diff to lockup if one wheel is spinning to fast.

I'm with you Jughead!!! The "anti spin" feature is worthless!!

The defenders of the AAM TracRite must live there lives "on road" because it is useless "off road".

 

Ha Ha Ha.

Been there and done that.

After digging out my truck where it had been stuck for 12 hours I took mine to the dealer. I showed them how the "anti spin" feature doesn't work. Even the shop foreman commented "hey, that ain't right".

Well, to make a long story short, there is only a small paragraph in the shop manual on this axle. Basically is says " if the vehicle can move forward and backward" there's nothing wrong with the unit.

I'm installing a front E-Locker very soon.

 

I have often been in situations with one wheel in mud and the other on dryish pavement. Both rear wheeels spin equally. When stumping I have three wheels that will spin.
