What does a broken LSD (1.5 way) feel like?

[TachPHD]

I have a KAAZ 1.5. When the pumpkin was in my previous car, it did clunk. That is typical. I changed the fluids out with KAAZ's gear oil. The clunking decreased drastically. However, the pumpkin has been sitting around since December of last year, with less than 500 miles on the new fluid. I installed this new pumpkin into my shell now and it clunks like hell! The rear end feels like it is loose and acts as if it were twist stressing as I turn. Going through turns at around 15 mph, it feels like when you're in first gear and driving and letting the gas in and out, the car rocks back and forth. I know the LSD is locking in and out causing this. I recently just did my first drift event with it. Could it be that the fluids went bad as it sat around and I need to fix it, or are the plates in the LSD going bad?

Have to figure this out because its getting annoying as my DD. Thanks

Did you take the diff out of another pumpkin? If so you didn't do the backlash right. Even if you didn't change pumpkins get the backlash done right, that's probably most of your issue. And by shell it kinda makes it sound like this car is stripped vs the other one not being so. That just makes shit back there louder.
