Does your wheel autopilot work well?

[AndyBC]

Yes mine squeaks as well.  It's a slow and steady creak in my case, not too excessive.  When I close my eyes I just imagine that it sounds like the creaks and groans of the wooden ships of old     Apparently the cause is due to the rollers in the wheel drive.  Raymarine advises to open up the drive and apply a very light smear of light marine grease to the bearings (but take care not to contaminate the belt friction surfaces).
