Triflow in the pin point applicator bottle. Takes very little and I last did it 3 years ago and all is still silent. I even use it on the kitchen cabinet door hinges and the aerosol for the hinges on my cars.
Boeshield T9, Fluidfilm, garage door lubricant. The Boeshield and Fluidfilm are similar and act like a penetrating wax. Seeps into the bushings and the solvent flashes out leaving a waxy film behind without a sticky mess.
