but does it really lock the 2 sides when 1 is loosing traction
[/ QUOTE ]1. Yes Limited Slip does work...Remember "PosiTraction"?
a. Both wheels are turning, splitting the engine torque,
b. The "spinning" wheel is not being used for traction,
c. But to lock the differential,
d. And little traction applied from this wheel,
e. But since the other wheel is also spinning, and has traction,
f. The Jeep can move at reduced power.
2. However, the degree to which it works is the question.
3. Like the Ryankopecki said, they can be broken.
4. Remember that the LSD has to be intellingent enough to:
a. Unlock when not needed.
b. Lock when needed.
5. It's like the old joke about the Thermos Bottle...
a. How does it know to keep things hot?
b. How does it know to keep things cold?
6. The intellignece is engineered into the springs, plates and clutch material.
7. If the engineeered specs are exceeded... the LSD fails.
8. Simple as that.
9. So, when the LSD's specs for applied torque, friction, etc. are exceeded,
10. The LSD fails.
12. This, of course, would happen when under the most stress,
13. That's usually off road, on the trail.
14. For mild off-road the stresses can wear out an LSD,
15. DIff fluid contians a friciton modifier to reduce clutch wear,
16. If it burns... then the LSD is quickly toast.
17. And it's a point most Jeep owners ignore.
