How much of that GM Posi additive should I put in my Moser 12bolt? I used one bottle, but thats the same about I put in my 10bolt. My rearend makes clunking noise when I go around tight turns/hills, and a couple guys thought perhaps I needed more. Opinions?

 

The Eaton posi in your 12-bolt is just a little noisier than the stock 10-bolt. Using more additive actually decreases the "posi" effect some. I only use 1 tube in my 12-bolt, i'd rather it not slip much at all.
