I describe it as "hell". I'm hoping swapping out my lightened flywheel cures it...I can't stand it. Once warm it rattles at idle and on decels. The worst is driving with the top down and driving past curbs or buildings where the sounds bounce back and I can really hear it, louder than my freaking exhaust.

OK, so the other night, on my way home (about a 1/2 mile from home) the sound started to happen ALL THE TIME, not just on decelleration anymore. Decided i'd drive my other car for a few days (240SX) until i could get under it and see what was going on. then a few seconds later it got MUCH louder and started to sound like my diff was going...then the vibration started....then i pulled in my driveway....it was DEFINETELY from the diff area so i'm assuming the diff's gone, (which is why i've been looking at diff options the past few days) but reading through an old post made me start to think that the diff might not be completely gone, maybe i can replace just the stubshafts for now, and upgrade to a 1.8 in a few months when i have cash.......any input is appreciated.
Thanks,
Brian

I have never had to pull mine apart, so i'm not sure exctly what could be causing it, but have you pulled the diff off? If you have I would open it up and check the ring gear, see if the coast side is chewed up, check for preload and endplay. Sounds just like a misadjusted ring & pinion but I doubt it would just get whacked like that out of no where.. One downside to having a 7" is I never get to play with it because it never breaks. :(

but is there a way to crack open the diff and replace just the ring gears for cheap to last me a few months? or is it just as expensive to rebuild it as it is to replace it?

Replacing just the ring gear (if that's indeed what broke, and not the pinion) requires basically the same exactly amount of work as replacing all the innards because you have to re-set your backlash and pre-load after R&R'ing the ring gear/LSD assembly. Either way the diff. has to come out of the car.
