Yes thankyou junkie,I know what an lsd is and how it operates. I was told the lsd was not activated until a certain amount of pressure is applied much more than you can create with your hand! (well maybe you could) And was also told some of the older diffs which were lsd werent necessarily printed on the sticker. This is why I gave the part#no. at the very beginning of the thread,can someone look it up. The only reference material I found says it is an open differential.
