Ok,
I recently pulled off my differential cover to inspect the diff and my posi unit. I have a bent axle from spinning out and curbing the car and wanted to make the the axle flange is all thats bent, and that the guts of the diff are ok (they are). When I was in there though, I noticed the posi unit looked a LOT different than the pics I saw here http://www.gnttype.org/techarea/pictureguides/rear/stock.html at GNTType.org. So i posted a thread in the general tech section, and after a few replies, I learned I had a Gov-Lok (lock?) rear... its apparently sort of hybrid clutch-type limited slip and full locker.... it allows some slippage, but if the amount of slippage between the two wheels becomes too great, it locks both together... but only under 20 mph, or something like that. Apparently its used mainly in trucks, where it has recieved a BAD reputation as being failure prone. Needless to say, I was not happy. I assumed a previous owner had replaced the stock unit with one of these for some reason (maybe he destroyed the stock one, and a gov-lok was cheaper to put in?). Then on that thread, Eric Fisher posted that he thinks this was the type of limited-slip differential offered on g-body's in 84 and 85. The link to that other thread is http://www.turbobuick.com/forums/showthread.php?t=179456
So I was wondering, those of my fellow hotair owners with limited slip differentials, what type did yours come with? The 86/87 clutch-type (as shown in the gnttype link above) or a gov-lock (which i will attach pics of). I'm just curious to see if mine is stock, and if so, to see what kind of abuse they can hold up to (since they have a rep for bein junk). Thanks for any and all info guys!
