Traction device in rear axle?

Does anyone know how I can tell if my Dodge has some kind of traction aidding device in the rear axle? If I'm in something loose like gravel or grass and I slip the clutch a little quick it leaves two tire marks, but hell the things a diesel and its got plenty of torque![img]/wwwthreads_images/icons/laugh.gif[/img]

Re: Traction device in rear axle?

Take your VIN number to the dealer ship and have them run a computer print out of all options your truck came with. It should be free, i've had it done on two of my vehicles. And it will tell you what axles you have, gearing, and traction device, either a limited slip of open diff... SUPERSWAMPER

If it's got a factory limited slip it will have a tag on the diff cover that reads "Use Limited Slip Lubricant Only". At least my '95 did.

I forgot my factory window sticker was in a book in the glove box, previous 2 owners were nice enough to save it. It says I have the anti-spin differential, is that basically a limited-slip? Maybe someone can tell me.

Re: Traction device in rear axle?

Yes, its a limited slip. I just did the fluid in my rear axle. Its barely noticable, as the clutches are in the sides of the carrier, behind the sidegears. One note...if you dont put the "special fluid" in, it WILL chatter. Note #2. The "special fluid" better be pretty damn special...it comes in a nail polish size bottle....like 2 ounces for about $12 at your "friendly" dodge dealer.

What if you lifted the rear end off the ground and turned one tire forward? If the other tire turns forward also you have a rear traction devise. If the two tires go in opposite diferctions then they are not connected. I think.

Bigwish,

Thats incorrect. Most automatic lockers and limited slips require power input from the pinion (driveshaft) to lock. Thats how a Detroit Locker unlocks when coasting around turns...without power input from the pinion, it allows the springs to push the locking collars apart. lifting the rear end and turning one tire is the same as coasting around a turn, to the traction device....

OK then void what I sayed. And thanks for the clarification.
So does it work with a welded rear and a spool?

Re: Traction device in rear axle?

An axle with A welded diff or a spool will ALWAYS rotate both wheels in the same direction at the exact same RPM, therefore you test would be valid on that, and you'd have to havea tire scrub and grind on the pavement making a turn, making these two differential options mostly for off-road use only.
