Series Swivel Hubs To Grease or Not To Grease

[Bullet50]

My understanding is that the series swivel hubs were designed to rely on oil splash generated by the u-joints spinning in the hubs to lubricate the top bearings. For this reason, free-wheeling hubs should not be used for longer bearing life. The one-shot grease is fairly fluid at high temperatures. I would not use this grease in a cold climate. My Rover operates at warm temperatures in New Mexico and I am using the one-shot grease, for now. I replaced the stock filler-plug with a brass plug tapped for a grease fitting and use a small grease gun to fill the hubs, less messy than trying to squeeze grease in from a funky plastic bag!
