Thanks for comments on ice and snow driving. Looked over and under truck. 1..Question is the build/sticker line item Anti-Spin Differential Rear Axle @ 300.00 and the Dodge service manual calls it Trac-Rite the same thing. I guess they are just wanted to check.
2..Can i check it by jacking up rear end and spinning tires. was reading something about both tires should spin same direction with LSD.
3..Also someone said that if I put my small spare size tire on with my 35"s it will ruin or destroy LSD.
I thought it was very interesting post on how LSD will put you sideways based on forward resistace. I have had it happen and thought the LSD should have pervented it, was on wet ground every time. I think weight in the back is what i need.

 

Trac-Rite is the AAM name for this particular model of "limited slip" or whatever you might want to call it. Anti-spin is a Dodge generic term for whatever happens to be the one they are installing at the time. The old Dana axles had a different design, but Dodge could still call it anti-spin if that was it's function. I think Dana calls theirs trac-loc. Neither one is a locker.

The AAM design in the third gens doesn't turn both rear wheels in the same direction when jacked up, like the Dana one did, because it's not a preloaded clutch design. It's actually hard to tell if you have it or not. They are very mild and act like an open design most of the time. They limit the "slip" the most when under heavy torque and rolling along, so it's hard to test them clearly.

I wouldn't run a small tire on one side of the rear for very far. But it should tolerate it at low torque and fairly short distances. Certainly better than a Dana trac-loc. If you must do it for a longer run, then put the spare on the front.

You might also hear someone say the diff needs friction modifier. Not in the AAM axles, but yes in the Dana with trac-loc.

 

Thank you, great info!
