Default Discus 2 rudder stiff help please

The rudder on my D2b has become very stiff on its hinges during this season. I disconnected the cables at the rudder horn, and it's clear the problem is in the rudder not elsewhere in the control circuit. Removed mylar seals without effect. No visible damage to the rudder, and no foreign objects visible between rudder and fin. Before I remove the rudder, has anyone out there encountered a similar problem? Glider has 650hrs TT, always hangared.

Thanks in advance for all suggestions!

The rudder rides on two surfaces that you could try to lube without removing the rudder. A lubricant with an extension nozzle should reach both. That said,
the rudder is relatively easy to remove (one nut). It is probably a good idea to remove it and clean the hinge points properly.
