creaky zoom rocker

[wannabeapilot]

hey guys ive had my hmc 40 for about 3 months now and it just recently started making a very annoying creaking sound when i use the zoom rocker ,and its not just loud enough to hear because of camera audio ,i could hear it today when i was in an auditorium during a very loud musical
any one had any problems like this?
any suggestions for some safe kind of lubricant to use on it?
