Yep, the LS can wear out. They are nothing more than wet clutches between both axles. Sometimes you can change the fluid but don't add the friction modifier and the clutches will not slip as much. Wet clutch style LS's are rebuildable.
Ford built a Hemi back in the 60's or 70's. (427CID IIRC). A lot of cars today are hemi's, they just can't use the name...copyright infringement. There were hemi's before Chrysler made the name popular.

yes they can wear out but also dont confuse the fact that if only 1 wheel spins its not neccesarily wore out, they are limited slips, not lockers.
and to start- when chrysler's hemi first hit nascar in the 60's ford came right back with the 427 sohc. only a few were ever built but in stock form they hit over 650 hp. nascar officials said flat out no so they scrapped the idea, the timing chain alone was 6 or 7 feet long. after that failed ford came up with the 429. the origonal 429 was a true "hemi- head" motor. but rules for nascar at the time said that if it was in nascar it had to be sold on the street and when the "hemi" 429 hit the roads it was way too much for the avg joe to drive so they redesigned the heads and the 429 that most of you are familiar with was born and then later down the road the 460 was born from it.....
current production motors if i recall used hemi head design, the 1.6 in the older escort gt's were hemi-heads, and i thikn the 2.0's may be as well, i cant recall all of them but the hemi design is used by many manufacturers currently

The flat head you're talking about was an aftermarket part.....not sure if it ever went into production. All I know is that i wanted a set of them for my very first engine rebuild as a kid....a Ford flathead. BTW: It those heads were made by a guy named Duntov, the father of the vette and many other innovative ideas.

Limited Slips are designed with clutches in them, as they are the differential material that binds the axle paths together. Once a cetain level of torque is reached, the limited slip hits it limit and is free wheeling. So, loading it up can cause it to break free, especially if the clutch material is gone. As long as the wheel speed is matched and torque is not applied with enough force, the limited slip limits the slip in the axle path.

True as said. Most of the stuff we see is. It's was the easiest to lay out in an explanation. Gear sets and dog clutches are a litlle tougher to visualize. Even the break out drawings for them can leave you guessing if you've never busted one apart.

so its possible that if i change the fluid the LS could work better?
i can't believe the response on the hemi question.

The force on the disks in a clutch pack in a clutch style limited slip is increased as axle torque increases.
This means that if one wheel is on a real slippery surface (or has little weight), the LS won't apply that much torque to the wheel with better traction. You can increase the torque by loading up the axle with the brakes on and easing off the brakes while staying on the throttle.
Just remember that in 4 LO you have more than enough torque to bust u-joints and axles.

its a possibility but dont hold your breath, as was stated somewhere earlier in this topic dont add any friction modifier to it to get a little better "bite" but if its never had any added in its service's through its life they may be burnt out
