Clutch-type LSD questions...
I'm trying to determine if the clutch-type LSD on a salvage '87 Turbo is any good (the car isn't a runner). It appears to have been leaking oil out the pinion seal, and it is very difficult to turn the axles, even with the calipers removed (to make sure brake drag/seizure wasn't the issue), with the gearshift in neutral. Initially when I turned it, I could only turn the right hub, and the left didn't turn at all. After a few turns, I was able to turn both axles, although it was still quite difficult, and the left side spun backwards from the right. I know there's some basic things that will identify a LSD from an open diff, but can't remember what the expected results should be.
My questions:
Should it be difficult to turn the hubs? And with both rears in the air and no drag from the brakes, how should the one not being turned move - ie, together, opposite direction, or not at all? Does it make a difference whether the tranmission is in gear?
Is any of this relevant to my trying to determine if the LSD has any life in it?
Bonus question - what would (should? - I'm assuming it's the original diff) the final drive ratio be on an 87 turbo?
thx in advance...
