Dripping (possibly Moen or Kohler) faucet disassembly

[pinchepooch]

I am not sure if this is Moen or Kohler or not but all the other faucets are. It has a drip from the cold side (if I turn the cold water off underneath it stops). I cannot figure out how to change the o-ring on this thing to stop the leak, any ideas? Thanks in advance.

Apparently as simple has opening the faucet 1/2 turn, then the nut came right off. I got the tip from this post. http://www.plumbingforums.com/forum/showthread.php?t=7631

Actually quite easy to fix. Took stem out and was thinking I would have to replace O-rings, not the case, got the whole stem and all for $8.99 at McCoys. Danco part # 6S-1H/C.
