in the search for why my diff was sounding even worse than normal i decided to tear it down to check things out. when i was under the car initially i noticed the output shafts had a lot of play in them so i pulled it from the car and dug in. bascially what i'm finding is that the plates have likely worn or the cone springs are worn out, taking the preload off of the plates and letting the side gears move around inside the diff. it still locked up fine just sounded exceptionally loud and would lock/unlock a bunch at light throttle even around large radius turns.
hopefully i can score the new "super q" guts for this thing as a rebuild kit. kaaz claims it's much more quiet, locks just as well, lasts longer, and doesn't require figure 8's in a parking lot for 30 minutes straight . i believe it's just some specially treated clutch plates so it should all go in the older housing just fine.
damn erin. you so manly. hope you get the parts ya want and it works out. been hearing about how pretty nothing can keep ya down at road atlanta and all ya do is blow past everyone out there. get this diff figured out cause i wanna see this stuff in person....hopefully FOERST person with a wheel in my hands.

after studying the diagram for a couple minutes i realized there was nothing outlandish going on in there and pulled it apart. it's actually pretty simple since everything is the same on both sides.
there's pretty much the housings, a couple of thrust washers to ride against the side gears, cone springs to preload the clutch plates, the clutch plates themselves, side gears, and then the pressure ring (which is what determines 1/1.5/2 way operation). inside the pressure ring is the pinion cross shaft with the 4 spider gears. the only thing to be careful of is if you're re-using the old clutches you want to keep them in the same order they came out in so the wear patterns match up.

Not that you would know anything about the joys of diff testing....
