Limited slip on sticker but not on truck???

[Mobius1]

Or maybe I am mistaken. I bought my truck a little over a year ago, and it has limited slip ($285 option I believe). Just this weekend I was rotating my tires, oil change, fuel filter etc. No maybe I am wrong or is it different with AAM. I was always under the impression that if you turn one wheel one way and the wheel on the other side goes the same way you have limited slip. However my wheel actually turned the other direction. Does it work differently with american axles or was there an error in production on my truck? Iwouldn't put it past dc to mess uuo something like this after I just found out that an srt-10 motor blew up after 100 miles b/c the wrong spark plugs were put in it from the factory



Any help would be appreciated!!!



Thanks

pull the cover and find out. my CTD didnt have the tow mirrors that were on the build sheet. they put them on free. thing is that was two days after i bought it, might be hard to show that after a year... .

some limited slips are inertia operated. try jacking one wheel in the air and spin it real hard it should hit hard and stop the wheel. thats the diff applying both wheels. with one stopped it sounds like somethings broke in there but its not, just the clutches applying. cant really feel it on the road though.

OR the more fun way to check BURN UM, if theres two black marks then youve got a limited slip.

I believe the L/S diffs are an inertia activated. That is why when the fluid is changed they recommed you do several tight figure eights to adjust to the new fluid. Could be wrong though.

There should be a tag inside your glove box stateing what diff. you have, at least on my 04-5 there is.



AA uses a torgue biasing differential axle made by Quaife. It works like a open diff. during natural driveing. It is not like the Dana. At least the Anti/Spin functions differently. No clutch packs like the Dana & no friction modifiers needed other than the reg gear lube.

Yeah I have a 3. 73 limited slip axle. I guess when I rotated one wheel and saw the other one moving the other way. I thought it was not a limited slip

Get one tire in grass and another on pavement -- nail it. See if it spins the one on the pavement.



John from Floor-It diesel had the limited slip on his window sticker, but the diff was really open. Factory error.

Antispin differential

Mine is called an antispin. The AAM uses a helical gear differential and works very diffferently from a clutch limited slip. I have had good luck with mine locking in but many have complained. It is similar to a quaife differential. Look at this-http://www.quaifeamerica.com/differentials/diffs.htm there was a better sight listed on this forum a couple of months ago but I can't find them.

Call your dealer service dept. and have them run your VIN #. This will tell them what your truck should have come equipped with. I went through the same thing you are now thinking that my truck had come equipped with a posi. rear axle. I have found that adding about 750 lbs. of ballast weight in the pickup bed made a huge difference in traction if you have that type of an issue.

The torsen type differential will rotate both tires in opposite directions when both are off the ground just like an open differential. Perfectly normal.

come on aftermarket. we are all :{

I thought mine was open too, I went to doge and complained about the other tire rotating the other way. They checked my build sheet and said it was limit slip. The mechanics didn't know what to say when they jacked it up. We took a new truck off the lot and checked it and the rear seamed open to. There just happen to be some dodge factory people there and my salesman talked to them since the shop didn't know what to say.

They said it works as a possi when both tires are on the same kind of surface. And it acts like a open rear to get better gas mileage.

I told them about the time I pulled over on the highway and the passenger side tire were on ice and the drivers side was on the road. When I hit the gas the passenger side spun like it was an open rear. This has happened more than once. And Iwas upset spending money on a unit that's a semi limited slip rear. I just told them that this rear is a bunch of BS.

This is a fundamental misunderstanding of how a torsen-type differential works. A torsen unit is a torque multiplying mechanism. What is anything multiplied by 0?



One wheel on an extremely low-friction surface will spin with a torsen differential. You must apply some brake to provide some torque to multiply!



I think the torsen system is a great idea, but Dodge has done themselves a disservice by using it because at least 8/10 people have no clue how it works and so they complain that it doesn't work.

Thats what I thought. I was just used to seeing the how the dana axles work. My diff seems to work fine in snow, crappy road conditions when there is a little weight in the back. When there isn't any weight in the back it doesn't really work too well. I ususally put a couple of sand bags in the back during the winter.

So what you are telling me, when I have one wheel on ice and it's spinning I'm supose to put the breaks on and give it gas also. Like power braking to move?

Yes, absolutely. I use a little parking brake since I have a manual. Doesn't take much. Results are much better.

I want a locker.

I want a locker.

I just want an LSD that is predictable... and that works like the power loc in the Dana's... these suck in snow as you cannot get enough biasing between wheels to do any good (hence, no positraction)... the drag race boys might like these, but in real world driving in snow, they all but suck.



And FYI, I get one-wheelie-peelie more than I get posi... the only posi I get is when the wheels are on pavement... anything slipperier and no posi.



I'm waiting for the Detroit to be out a while... they are already having issues with the prototype in the GM versions.
