Vintagers,
Consider this technique used in the dual sport motorcycle world for wheel bearings...remove the rubber seals, wipe out as much old grease as possible with toilet paper, do not use solvents or degreasers, wipe in new grease, reseal and adjust, ride.
Wheel bearings on my BMW are around 150K miles and running strong.The machine has been to the bottom of S.America(Tierra del Fuego) and Panama twice using ths technique. Regrease every 30K or so.
Same for the steering head. This works, is quick and easy.
