That's not how it works, that's not how any of this works.

 

I'm glad I'm not the only one to see LSD, realizing what the OP really meant, and thinking of Purple Haze, the Beatles and that corvettes can fly subsonic.

 

Did you try changing the Driving Mode?

 

speaking of differentials, I always thought this was the best explanation of a diffrentrial. (open diff) it's old, but very easy to understand!


Here is one about all diffs


I'd have to say, ice or mud, if one wheels spins in these LSDs, the one with most traction (one not spinning at all) should have some power to move the car.

 

If both wheels spin the same the car would slide which ever way the pavement is tilted trying to push the front end. Pre loading of the side gears with spring pack is all the friction there is to drive stationary wheel through clutches. A lot more pressure is the result of the spider gears trying to climb out of mesh with side gears when there is a lot more traction to be had! Thus the reason for the new electronic controlled diff maybe! Maybe traction control should apply slight brake to wheel thats spinning so more torque would go to the stationary wheel!

 

There was no way for the Diff to know to transfer to the other. Ice had no resistance. The rear end thought it was cursing along basically.


If you want to check operation of the limited slip.. Try this.. Go to a nice dry spot, take traction control off. Put in gear 1st/D... Push that right pedal to the floor after realeasing all other pedals... Enjoy... 3-6 seconds will do ya...let off the right pedal.. remove grin from face.. Do a legal U-turn... Go back to starting point.. If you see 2 long marks.. Everything is fine with the LSD.. If one... Go see your dealer...

it's not the resistance. it's the lack of traction (where one wheel spins and the other doesn't)

am i wrong?

 

Cool videos

That first one is super retro

 

It is resistance basically, The spinning wheel had none what so ever being on ice. It is the same as if the car was jacked up or if the car was making a turn (Knowing the outer wheel turns faster) and the design is to allow the wheels to turn at different speeds limiting the slip allowed. So the ice was allowing the other wheel to slip.


With that being said, under torque or heavy acceleration changes the dynamics of the LS rear. It basically locks just like a Posi unit does.

There are basically 3 types (4 really a spool for racing) of rears. Posi, limited slip and a Open diff (one legger/ one burn off mark).

 

How is that any diff then getting one tire stuck in mud though? isn't the purpose of the LSD to give power to the tire that has traction/resistance?r

 

OP is this you?

 

All I can say is. I doubt he had any torque to get the clutch packs compressed. With light acceleration the car/diff did not know to transfer power. Limited slip acts as 2 different types of rear ends. and to change from one to the other you need torque applied.


Regular driving it acts as a open diff. lets you roll straight, make turns and is less abusive on the gears.


Under torque the Diff "senses" high torque and low torque on either axle. Example is: Dropping the clutch and smashing the gas pedal. Both tires will basically "Lock" together with equal power causing equal burn off marks (but if you really look closely at a LSD burn off mark, one mark will start just before the other by a inch or two, this is because it took time .o2 seconds for the clutch packs to be compressed) That is the most extreme example. Now at other times like being stuck in mud with only one tire and your not standing on the gas like an idiot, but giving it more than usual it senses the torque and starts looking to transfer the power. It is not always going to send the power to the "Stuck" wheel. It will transfer back and forth between the two.


I have yet to see 2 limited slip rears act the same. Some are soft (meaning they hardly go into posi unless max torque is applied) others are spot on and some are damn near Posi all the time.
