What lubricant does Sony use for the PS3 analog stick?

My warranty has expired on my controllers, and I'm looking to take them apart and replace the lubricant since they are sticking/squeaky. I would like to use the best lubricant for this which is why I'm wondering what lubricant Sony uses?


Solution 1:

For my ps2 controllers I used rubbing alcohol to fix that issue. They both work great and I have had the same system and controllers since 1998.(Still use today)
