Viscous LSD B1G Differential - 1G

Does this mean I should have added some sort of LSD additive last time I changed the fluid in my 90 GSX??? I screwed up and did not add any additive to the rear end. Now the car makes a grinding noise when decelerating... :thumbdown Any help is appreciated.

I'd like to know the same thing. Hopefully someone who knows will offer their help.

The LSDs in DSMs are sealed, viscous couplers. They'll never realize anything's been added. LSD additives are for clutch-type LSDs.

Many high mileage 1G's have some sort of coast down rumble. My car does the same thing. I think it's because the rear diff pinion has too much freeplay, but I don't care enough to fix it yet.

Lately I have been driving the car much harder trying to get it tuned for the track and the grinding sound seems to be much queiter now.

yeah, i looked again at my rear end. My placard says "b1h" not "b1g". What's up with that?? It is limited slip.

mine is a three bolt; yours is 4...otherwise very weird.

B1G is the 90-91 and the B1H is 92 and on. I don't know what year the B1H ended. They are the same. They are both 4 bolts and lsd. The difference is that the half shafts to the hub are 3 bolt on the B1G and 4 bolt on the B1H.
