anti-spin spec(ed)didn't get!Dodge Rip-off

[monkfarm]

I got stuck the other day (first time) and found out I don't have the anti-spin differential the spec sheet (that I kept from the new purchase in 1999). The anti-spin option (I paid $285 for) was not installed or ???. That is (the same as limited slip isn't it??) One set of duals definitely did not spin, and I would have been able to walk out of the (stuck) situation I was in.
Has anyone had a similiar problem where they ordered some option (didn't find out about it untill much later) and found out how to deal with it??? Who do you deal with ??? I will call the dealer, but I'm not too excited about the dealer. (Jeff Belzer Dodge in Lakeville, MN.

You may have the un-Limited Slip version of the differential as many of us do. I even had my clutch pack replaced under warrranty. The components are there, just not very tight. I plan to change the differential oil and use less friction modifier to see if that helps. Just haven't got around to it yet. Has any body else tried that?

By the way, my LS falls within spec with the torque wrench, but still waaaay to loose for the money I spent for it. It's no better than an open differential.

Try changing your diff fluid and don't add any friction modifier to it at first, and then you can test your LSD out. Then add small amounts of friction modifier until it doesn't chirp.

Monkfarm,
Not to be the bearer of bad news, but everything seems fine.

You are not the first to mention this. .

It appears most people expect an antislip diff to perform like a true locker. One example would be the imfamous Detroit locker.

Having owned both styles... I can tell you the way in which they function & operate is quite different.

If you look in ol' Webster. . ANTI means "against" Not STOP,HALT, etc...

As a rule of thumb. . antislips only transfer "about" 60% of the available power. Hence if one wheel has very little available traction... The other wheel will appear to spin as if it were in an open differential.

On the other hand, antislips are easier on tires, which also equates to easier turning/steering. They are also quieter than a locker. Which tends to chatter or click while turning. Ever made a sharp turn in 4wd? A locker gives a "mild" version of that feel.

Like most things its a compromise of performance vs. usability/practicallity.

A locker might have kept you from getting stuck... But you'd probably curse at it everytime you wanted to make a sharp turn.

The Dodge anti spin works, but has the frustrating quirk of not working when starting from a dead stop in very slippery conditions - usually when we need it the most #ad
Next time try adding a little parking brake to load the LS a bit. You can verify your LS works by trying to do a burnout on cement. One wheel will start to leave a black mark and then the other wheel will lock up due to the LS and you'll either leave 2 black stripes or stop leaving any stripes depending on how much power you put into the burnout. Lockers work well, but have an annoying clunk when they engage mid corner in tight turns. This can cause the truck to step sideways and be a little scary if your not expecting it. just my opinion...

I'm sure that you have your ordered option. A quick check would be to look for a tab hanging on your rear differential cover stating to use friction modifier. The other test is to jack up one side of the truck and you will find that it takes quite a bit of force to turn the rear wheels by hand. I have heard that these trucks slip even worse when they are not equipped. Good luck,

I used to curse my LSD until it did everything it was supposed to the other night. On the ice and snow i got stock like an open diffed truck more than once. But i pulled a 3500lbs trailer out of a field the other in my 2wd 2500 5spd and had a hell of a time but spun both rears the whole way out. I think most of my problem was the heavy Cummins sinking my front tires. As i was stuck without the trailer once. My dealer was more than willing to look at my LSD but i didn't take it in sicne the night before it worked great(after i made my appt of course) Enjoy

I think you guys nailed it, the LSD works great but... not with the power the ISB puts out. MY 1/2 ton w/LSD can go through anything with no slipping. 2 weeks with the ISB and I already know that it can't handle the power. Air Locker is the solution!!

Why didn't you shift to 4 wheel drive?

 

[Alan Reagan]

I didn't use enough additive when I changed the lube on my 98 and it chattered like crazy when I would pull off making a right or left turn. Put some more additive in and stopped the chattering.

After having both Dodge and Ford LSD's, I think we are expecing too much from them. By design, they will cause both wheels to put power to the ground when there is a slight difference in traction from one side to the other. Now if one wheel is on ice, and the other is on dry pavment, you may be able to move forward slowley, but put some power into it, and its going to slip. Then after it slips, it gets hot, and slip some more, and gets hotter, and slips eaiser (this story would go on until you let off the fuel and let it cool down).
In order to put the amount of pressure on the clutch pack to needed to compensate for the power we have avalable to apply from the motor, we would have tire squeal with wheel hop when we go around a corner.

Yes, I have an LSD rear, and yes at times I sware it don't work, but most times I don't even know its there (because its working right)

Thanks for your feedback. Incidently, I did have it in 4 wheel drive (it acted like 2 wheel drive #ad
ne turning in the front, and one turning in the rear); but it was in about 15 inches of snow out in a field pulling a 18 ft trailer. (We were getting wood for our taylor outside wood-burning (heating) stove). There was a crust on top of 1 foot of snow, a farm tractor had been in there before, but his tracks were about 2 ft. wider then mine. I live way out in the sticks in the hills by the missippi river valley (by lake pepin). . . Thanks again for all your helpful replies, I would have went to the dealer with flames coming out of the top of my head. I will check this out, and educate myself before I make a move. Thanks

Sanddemon?!
what's an airlocker?? I have an onboard air compressor for my firestone air bags. (Which work really good!!(better than the cheapo AIR LIFT (chinese mostly) that i had on my powerstroker))

An Air Locker is a nifty litle device. It's a locker that only comes on when you activate a solenoid. So you have open diffs otherwise. Much better than an LSD because it's fully locked when activated.

ARB is the leading mfg and all the off-road shops have them. I don't belive they require any air flow, just 80psi to engage. They are around $600 though... #ad
Can be put in front and rear.

Been there, done that!!!

Per the big orange Mopar Bible, acceptable specs for testing DC's POS LSD's are anywhere between 20-200 ft. lbs before it slips. Gee, could our little Cummins put more than 200 to the rear wheels. If it didn't, I don't think any of us would want one.

So even if you're at the high end of spec, IT WILL SLIP, period. #ad

This 200 lbs sounds right. But keep in mind that the 200 lbs will not come into affect until you have a difference of 200 lbs pressure between one side to the other. Thats why I say if one wheel is in snow, and the other dry, go slow and you will get out. When both sides have the same traction you will leave 2 marks (like Jponder does)

I don't think I am asking two much of my limited slip by expecting it to move me along a level surface with one wheel on grass (firm graound) the other on concrete. I've tried easing the power and I've tried putting the pedal to it. No action. The parking brake concept I understand but it has never worked for me and applies to open diffs. as well. I could windup my '95 gasser and lay tracks, so don't try tell me it's the power differance. My '95 would never spin one wheel, period. Yes the big diesel is heavier but my limited slip does not work! They replaced the clutch pack 3000 miles ago at 35000 and it is not working. Out of warranty now...

If your considering buying a ram, you might consider that it seems that many of us are not satisfied with the performance.

I would go talk to the dealer about this one. It sounds like they never fixed it right! Deal with them nice, its there choice weather they fix it now (38,000 miles) or make you pay. You might have a shot at getting it fixed. If they say no, I would go to DC. I mean the fact they "fixed" it only 3000 miles ago has to be worth something.
I am sure (or hope) there book don't read "if you can't fix it under warrantee, hold the customer off until the end of warrantee and its there problem".

Knuckledragger,

If you look at the charts, the Cummins puts out more torque off idle than a gas motor does at peak. So (even though I don't want to try it) if I were to nuetral drop my 360 at 3200rpm I still wouldn't get the same torque to the diff as a part throttle acceleration on the Cummins.

I wish we'd have gon through this a few weeks ago!! I busted my hump to get a 3. 54 LSD when I should have got an ARB.
