WTF One tire Spinning

[RottnDogue]

OK, I know it's childish but I can't help myself..... I've smoked the tires twice both times only passenger tire spun... . I know this by the Rubber I had on the side of my truck (only on one side). One place I checked Yep only one mark on pavement... . So I stop in my driveway and put my foot on the brake, ease into the go pedal and the tire(s) spin... . I stop pull up and two marks??? How come two mark now and one mark then??? The second time I smoked the Tire (one) it was the same method..... eased into it??? is it a problem with the rear diff. ? Or is it normal?

Do you have an LSD, or an Open Diff? if you have an open differential... you will spin only one tire most of the time. If you have a Limited Slip Differential, you can spin both..... untill it wears out, then you will have a single tire frier.

 

[RottnDogue]

How do I find out which I have?

Jack up the rear axle so both tires are off the ground and put it in neutral. grab one rear tire and turn it, if the other one goes the opposite direction no LS if it goes the same direction as the one you are turning you have a LS but its pretty worn due to the performance you described. I have LS and both rears burn the tires all the time.

I think the tag on the rear diff. indicates if it is an LSD.

You can get a complete build list on your truck by having the dealer look up your VIN in the DC computer. It will print a list of every nut and bolt and component that was on the truck when it left DC.

Cool... ... Oh..... Dealer... . Pardon me for being cynical but what do they charge you for that?

 

[AggieJustin]

Ken is right, you should be able to just look for a tag hanging off one of the rear diff cover bolts. I've got a LSD and the tag was on the driver side of the diff and was basically a notice to use limited slip diff lube.

Before you get all excited, remember that ....

the key word here is "LIMITED'. And there's a lot of tolerance in DC's specs for what is acceptable. 4X4 really means 2. 5. X4.

I have a sticker on the inside of my glove box door on the left hand side labeled "Equipment List". The last item on this sticker says, "Anti-Spin Differential". You may want to look to see if you have this sticker. I have a '01 3500.

Try opening up your hood, look under the hood up towards the front and in the center behind the hood latch. On mine I have a sticker there telling me some of the info on the truck. IE axles, gearing, limited slip, 4x4 (duh), paint codes etc. I've seen some of the newer trucks and they didn't have this sticker there, maybe they hid it somewhere else. I bought used and this is how I figured out what I had. I think the deal on limited slip is it will lock in both tires in "easy slip" conditions where the torgue is down like snow drifts and ice. It will not lock up when doing "burn outs" on dry non-slippery surfaces to save the driveline etc. If you have to have that, get an ARB, that allows you to have all the say weather it's locked up or not. You can get them for front and back, this is what the rock crawlers put on their rigs.

This is my 2nd truck with anti-spin, half the time I don't think it works. I watch both sides when I spin out of my driveway in the snow and half the time only one side spins. Both trucks were bought new and never abused so I know the rear-ends aren't shot. In parking lots turning sharp I can feel it chatter quit a lot. Is this normal or am I expecting to much from a anti-slip diff. ?



Thanks,

Doug

RottnDogue, the reason you're getting two tires to spin in the driveway is because you have the brake on.

Old trick to make both tires on a LSD lock is to partially engage the parking brake. Really helps if you're getting stuck.



Doug, it sounds as though you need to add some limited slip diff lube additive. A little goes a long way, try half a container then drive in several tight figure eights and see if the clatter disappears.

The sticker you have under the hood of your '98 sounds like the sticker I have in my glove box on my '01. My '95 1/2 ton had the sticker under the hood. Maybe Dodge moved where they put that sticker over the years.



With the limited slip, when one wheel spins a couple revolutions faster than the other it locks in plates that are basically just clutches. They aren't the best, but they do help. Over the years and continued use they tend to wear out and become less affective.



In contrast, a locker has gears instead of the clutches so they lock good and hard and don't gradually lose there affectivness over the years like a limited slip does. The down fall to a locker is when going around corners they tend to lock/unlock/click/make the tires chirp and are all around too unrefined and mechanical feeling for a "over-the-road" type vehicle. Because of this, they're not recommeded for front axle's do to their sudden locking action and are typically installed on vehicles that spend a great deal of time offroad. They're probably found on approximately 90% of the hard-core offroad guys rigs... atleast in the rear end.



This all brings us to air lockers. Air lockers are the best of both worlds. You have an open differential for around town and the less challenging trails and with a touch of a button you have a solid axle. Probably the only down fall to the air lockers is cost... beause of this, it seems like those that have them typically have them in the front end with a good 'ol Detroit Locker in the rear.



Driving on icy roads... . For me, I would rather have an open diff for icy roads. A limited slip is fine, but I would rather set myself on fire than drive around on an icy interstate with lockers (it's less stressful setting my self on fire). A locker is usually abrupt when it locks in and ubruptness is the last thing you want driving on ice. It would probably be enough to make you spin out or drive yourself right off the road. Limited slips are OK for driving on ice because they only allow the axle to lock up "limited"ly and not solid like a locker.

Illflem,

For some reason I was thinking that with less chatter means it will slip more instead of grabbing when it started spinning. I'll try a little more additive if that's what it takes. I've never changed the lube in the rear, only 3600 miles on it now. Still the stock lube.



Thanks again,

Doug

I agree with Ming, you snuck in there last time while I was still typing! Wife asked me how she should drive the truck on icy roads, I very simply said: Stay out of the turbo!! Like you said locking up on the ice isn't very fun unless your playing on purpose!! Going for the Dukes of Hazzard look at 50mph on the highway can make you suck a lot of seat up your a$$ in a hurry.

That's the thing I used brakes all three times.....

I did the same thing this winter with just a dusting on the road. Upon entering the interstate and going about a 1/4 mile, the TC hadn't locked up in OD. Not thinking, I did what I always do and get a little heavier on the throttle to lock it ,,,,,,,,,,,,,, and it did ,,,,,,,,,,,, YE..... HAaaa

Very gingerly letting off and bringing it back from a 45 degree angle, using both lanes and praying it will go down into the medium and not the guardrail, she finally straightened up. It only took about 5 miles for my knees to stop shakin. :-laf

Note to self: "Don't do that again ya big dummy"

Sure glad it was late at night with no traffic!
