Don't grease the pins. Especially not on the factory rubber boot. There's a chance that the grease and the boot may react and oxidize over time and cause the pin to bind. If you DID grease the pins, I'd take them off and clean the pin and the booth thoroughly and re-install.
The only time you SHOULD grease those pins is if you installed brass guilds. Since it's steel on brass, you need to grease it regularly to prevent it from binding. But rubber on metal? No.
The hell I don't! LISTEN, KID! I've been hearing that crap ever since I was at UCLA. I'm out there busting my buns every night! Tell your old man to drag Walton and Lanier up and down the court for 48 minutes!
