Ricoh MP 501. Squeaking.

[Practic]

Hello everybody! Looking for advice.
Just spent 3 hours trying to figure where squeak is coming from. First time I thought - was a fuser issue or paper exit area behind fuser, so I lubed gears there and put back unit - no luck. Then - tried different toner (I remember that had similar problem because of toner bottle on some other 501 machine once), but - no. Ended up locating problem - around drum area. With open cover - I pushed cover switch and it was quiet, and then I engaged gear to get whole drum spinning - that's where I found squeak again. Next visit I probably will start playing around with drum and dev unit. Just wondering, does anyone had similar issue before? I don't see any TSB about that issue.
Thank you!

There was a specific RTB regarding points to be greased on the 501 to stop squeaking. If you're struggling I can try and have a look for it.

Replace drum section, that should take care of it.
