Ok, full disclosure I work for a major auto OE, I'm Manager of Test dept. , 30+ years in the business, 25+ at OE and 5 at supplier level.

Guess there is NO R&D testing done on these Chinese knock-offs, they just copy/paste other designs and sell them?

Not having any service manual available should have been a red flag, hard to make one if you don't own the IP for what you are selling.

For these "missing" ahem - lack of need for zerk fittings, I have to hope they are truly sealed design (wheels), the boots on the suspension being tightly sealed don't let grease out nor moisture in, etc. ie, no service is needed.......

I respect what you did OLDKID, but I'll roll the dice here.
Maybe yearly I should dis-assemble the front wheels, ie take off the cotter pin and see the grease situation, and if needed try and re-pack them?
