Default Mainwheel bearing service / greasing?

My "generic comment", is, a bearing is a bearing, regardless of what it is used in.
Ball bearings may be different than tapered roller bearings.
Preload may be different.
A mechanical engineer (which I am not, but decades dealing with bearings and dealing with ME's) will likely say, a bearing is a bearing. What was the design, how do you service?
Almost no need to say, "too much lube", unless you're spreading lube onto composites that you may need to repair.
Don't be stupid on lube, but if you think it needs lube, do it.
BTW, WD-40 is NOT a lube.......
Period.........

I likely have 10 different lubes in my shop. Some stick, some penetrate, some are sorta composite safe, some deal with weather and/or loads better.
Whatever.

Oh, have a nice day.
