Jack the rear of the vehicle up, put in neutral and turn the wheel. If the other wheel turns in the same direction it is a posi-traction or limited slip, if the opposite wheel turns in the opposite direction it is not a posi. These rear ends give many problems though. I doubt friction modifier will solve your problem unless it makes a slight popping noise in very slow turns like in a parking lot.
That model # is meant for the front and rear differentials on a WK Grand Cherokee. I just called to verify this on my 05 4.7L Grand Cherokee. It's also used on some WJ models. It's Dodge's/Jeep's synthetic 75W140 lubricant. Use it if your truck/Jeep has the vari-lok differentials or the towing package. Also don't forget the friction modifier (if required), part number 4318060AB.

Changing the type of surface area can affect sliding friction because different materials have different levels of smoothness and roughness. A smoother surface will typically have less sliding friction as there is less resistance between the two surfaces. In contrast, a rougher surface will create more friction due to increased contact points and resistance.
Changing the shape of an object can affect friction and air resistance. For friction, the surface area in contact with another surface can increase or decrease, altering the friction force. For air resistance, a more streamlined shape will experience less resistance compared to a less streamlined shape due to differences in how air flows around the object.
Friction forces can be changed by altering the surface properties of the objects in contact, applying lubricants to reduce friction, changing the weight or pressure on the surfaces, or adjusting the roughness or smoothness of the surfaces. Increasing the friction force can be achieved by increasing the normal force or the coefficient of friction between the surfaces.
You can reduce it to a point it is not noticeable but can not eliminate it altogether. You can reduce friction through use of materials with lower coefficient of friction like PTFE or by changing the way the materials contact, say change a sliding one to a rotating one.
Friction can be reduced or overcome by introducing a lubricant between the surfaces, using smoother surfaces, or minimizing the force pushing the surfaces together. Additionally, changing the material of the surfaces in contact can also help reduce friction.
Surface and material affect friction by changing the amount of contact between objects and the roughness of the surfaces. Smoother surfaces with less friction will have less resistance to motion, while rougher surfaces with higher friction will have more resistance. The type of material can also impact friction, as some materials have a higher coefficient of friction and will create more resistance when in contact.

I am currently learning this in school; they can change amounts of friction by changing the surface. What I mean is, for skiers, put wax on their skis to decrease friction between them and the snow. Hope this helped!
