I have a 2 handle Moen kitchen faucet. Not sure of the age, probably 5 yrs or a little more. The spout has a lot of play in it and has begun to leak around the base of the spout out the TOP of the decorative locknut. I have replaced the plastic retainer clip under this nut as well as the o-ring right below it. No luck. I noticed there is a groove in this retainer that contains a split plastic ring with what looks like the remains of teeth on it. Definitely worn by looking at it. Question: I've searched all kinds of parts web sites, including Moen themselves, but don't see this in any diagrams. Is it possible to but just this part, or do I need to spend $30 + on an entire spout. Also- your thoughts on whether this is even the problem. Thanks a lot.
