I have a berringer nose wheel on my RV10. I'm doing my first annual. Anybody know if there is any special maintenance task or special inspections necessary on this nose wheel? I've searched through the Berringer documentation and don't see anything. So is there anything to do beyond the obvious, i.e., Axle bolt torque, check for tire wear, check psi? These wheels have sealed bearings so I don't believe repacking with grease is necessary, correct?
