In Reply to: lesson in differentials, please... posted by RM on September 11, 1999 at 21:09:54:
: Hi Everyone,
: I'm still unfamiliar with my '02 (i.e. I'm not sure what has and hasn't been done to it). I assumed that I had a regular differential until I "accidentally" dumped the clutch on my driveway. This left behind two, neat tire patches of equal length (about 4 feet long). I thought a stock non-LSD would leave one substantial patch and maybe a little or nothing on the other side. I jacked the car up and, sure enough, rotate one wheel and the other rotates the opposite direction. Since I have positive I.D. on the stock differential why the two equal tire tracks??? I thought this was kind of weird but it can certainly be chalked up to my lack of knowledge on how differentials work. Anyone wish to fill me in? TIA!
A spinning wheel represents wasted power. A LSD directs a percentage of that wasted power to the other wheel. In an open diff, the wheels are independant. In a LSD, a wheel can only turn so much before the other wheel has to turn
