I have a couple of tripod ball heads one being a manfrotto MN486rc2. It's about 2 years old and is becoming harder and harder to use. With only the slightest tightening movement becomes a very jerky affair which of coarse if useless for slight composition changes. I notice there is little to no lubricant left on the ball which going to be the cause but how do I relube?
I am presuming I can't just slap any old grease on there? Is there an accpeted method for this?
I have recently purchased a Gitzo lightweight ballhead and it's wonderful to use with smooth movement. I wouldn't want this to go the same way.


sorry I couldn't resist
