I'm interested in the answer too, as mine gets squirrelly as hell and after replacing joints, bags, etc. For awhile I was starting to think that it was some sort of delay in the DSC.
I can be on just rained on pavement where it's squirrely and can stop and punch it and it grabs right away without any slippage.
One mechanic said it's possible that the bag could have some wrinkle or alignment issue
Let me know if you have done anything to the rear end...
