hey, i broke driverside outer CV joint on aftermarket "performance" axel that i will not name right now. anyway it left me standed, the driverside axel just spun in the boot, the cv was completely sheered internally.

why didnt the oem LSD send power to the passenger side when it sensed the driverside spinning?

 

there is nothing wrong with the lsd, but i dont know if i can say that for you.....

 

i spun the bearings on an outer joint with my h22, and the lsd allowed me to still drive it into a parking spot. Not something you want to put miles on though

 

I'm not positive on the LSD in your R, but most types of LSDs rely on there being SOME traction on the "slipping" wheel - with your destroyed CV you did not have that.

This dude is correct, I think. The factory ITR LSD is a torsen type, and as he said, requires SOME traction on both wheels to work. If one wheel is up in the air or something, it doesn't do its job.

 

An interesting addition.. it wouldn't have helped in this instance, but if you have one wheel on ice or something, lightly apply the brakes, and the drag on the "slipping" wheel will allow the differential to apply torque to the "gripping" wheel.

The only thing that would have helped you there is a full locker, not an LSD. Of course, that would pretty much ruin it as a street car

 

The same thing happened to a friend's DSS driveshaft. It snapped at the outboard joint and ummm....we ended up pulling the entire tranny apart only to find the broken outboard joint when we were fiddling with the differential trying to simulate what happened. What a waste of time.

Heh, did the same thing with my car last year. Once it was up and tranny was in process of coming off (pulling axles), I found the axle had sheared off before the outer joint and inside the boot.

Unfortunately it did its job perfectly.

It's not electronic, so it couldn't sense anything and adjust accordingly. When you bust an axle with a torsen type diff, j00 screwed.

 

thanks for the replys.

would a kaaz clutch pack style LSD build friction in this situation to spin the other wheel? like mentioned before, just to get the car to a safe place to repair the broken axle.

i have a feeling this is going to be a common situation for me and i dont like the idea of being completely stranded.

btw: i thought the flywheel broken at first, visually the axle stayed intact, we only saw that was the problem when i applied power in gear and my friend was able to look under the car and see the axel shaft spinning in the boot.
