Mine had lots of noise so I put in two bottles of the additive and it has definately gotten much better. I think that it slowly gets better rather than just being perfect right away.

What is the ratio?
2 bottles of gear oil to 1 additive?

I start with 1 bottle and if it chatters on big radius turns I add another bottle. Usualy takes 2 bottles.

If 2 bottles wont help you have bigger issues. Instructions on limited slip aditive states NOT to over do it!!

Take it into an empty parking lot and do some figure 8's for about 30 minutes to work the additive into the posi unit...worked for me...
