There is a small hole at the bottom of the gudgeon that you can squirt grease into with a grease gun. Initially it won't do much, but the grease will eventually work its way down the shaft lubricating it.
So this seemed like a very promising direction. However, I called PSC and chatted with Thumper and he suggested there was no hole in the bottom of the gudgeon for grease to be squirted into. He asked I take pics of the rudder when out of the water to confirm the bushings between the top and bottom of rudder were still in place. I took the pics and sent to him. Nonetheless, the bushings looked fine.
Just to be clear, the noise is when we are not moving, just turning the wheel. When we are moving too many other noises to distinguish this one. But very clear rubbing, scraping when we move the wheel at dock. And quite stiff steering.
Getting back to Thumper's recommendation thus far, the grease nipple at the bottom of the steering pedestal is a likely problem point. Very hard to get to and really just a hole not a grease nipple per se (I will try to attach a pic of it). So maybe at least part of the problem??? On the other hand the rudder pole (not sure of correct name) is a very interesting possibility.
I will try to connect with Thumper this week and get further input and post accordingly.
BTW, thank you sailnet.com buddies and PSC owners! Once our equipment is older it takes a village to figure this stuff out! No longer mechanics that are familiar or tech support lines that care, etc. Really appreciate the ideas and conversation.
