AWD 1G - Rear Wheel Doesn't Turn.

[DSMsamurai666]

I have a 92' GSX. I was wondering about how the viscous coupling diffs work on this car. I was under the impression, becuase of the sticker in my door jam regarding the diff system, that on this car either all 4 wheels turn at the same speed or none turn at all. I was removing the driveshaft on my car the other day and when I was done, I decided to play with the rear diff while I was down there by turning the flange on the diff that the driveshaft bolts up to. What I noticed was that when I did this only the rear driver side wheel turned while the rear passenger side wheel stayed still. After this I remembered a time this past winter when I tried spinning my wheels a little in the snow while my friend watched and he said that all 4 wheels spun except for that same one, the rear passenger side wheel. At the time I justr disregarded it as him being mistaken.

So, is my rear diff or axle broken or is this how the system works?

Its not your viscious coupling. That is what provides power to the front tires after the rear tires slip. From the sounds of what your saying it would be your limited slip in your rear axle. That is seeing your car came with lsd or that someone didnt swap out your rear axle for a none lsd at one time.

In my expeirence with limited slip diffs if you spin one wheel one way the other wheel will spin the opposite way. If it were mine Id take the diff cover off and inspect the gears themselves along with the splines on the alxes to make sure theyre not damaged. Maybe you could take that approach.
