Re: Rear Differential...with all the recent talk
Traction control would not produce 2 uninterrupted black tire marks on the ground. What you would see if the traction control was the LSD would be a black stripe on one side then the other. If the TCS applies the brake to the spinning wheel then switched power to the other wheel you would have the effect I just described. There is also a third type of rear end called locked. In this rear end the read differential does not have friction plates and both sides of the axles act incongruence. Meaning 1 turns the other turns. I have a locked rear end on 2 of my mustangs. This is excellent for dragging and not so good as a daily driver but it can be driven daily. As mentioned in another post of this thread the name given to the limited slip is brand specific but is in effect the same idea. There is also called a open differential which is the true 1 legged wonder. Only 1 and only 1 wheel will spin and it will always be on the same side. My truck(God knows why) has this and it is completely idiotic for a ruck to have this.
The stock rear end in an srt 6 is differnat from the non srt6. we have a true limited slip and not an electronic. Hence the 2 black stripes as stated in another post. The TC'S and yaw(ESP) apply brakes to spinning wheels to obtain better traction and to maintain the point if direction relative to g force. Steering wheel is turned to make a certain corner and the lateral g's produced with the orientation of the vehicle is how yaw and TCs calculate whether or not braking is needed.
Example: Turn a corner quickly and the back end slides out. The change in direction of the steering wheel, the changes in direction of the g's informs the TCS that the vehicle is "sliding" sideways and in what direction. The TCS applies the brakes in an attempt to straighten the vehicle out to a direction it was previously heading. If you go quickly enough the yaw sensor and TCS can not react quickly as to stop the slide. I have done 360's (donuts) with the TCS off. Therefore the yaw control obviously did not compensate for the change in the direction of the g's.
