A couple of new owners have found "undergreased bearings", missing or not attached brake springs, loose bearing retainer nuts and damaged/improperly installed grease seals.

The number of those problems is extremely small, very likely not applicable to you, but, if you're the "one in a thousand" it's one too many.....

So, if you're the type that wants to know things are put together correctly, or if you're the type that goes with the flow and will deal with it if it happens will determine whether you feel the need to grease your bearings and readjust your brakes before the season starts or wait to see if anything happens and depend on the warranty to fix it if it breaks....

There's no "absolute practice" that goes with checking and repacking wheel bearings, so it's pretty much a personal decision. I don't like surprises, so mine were checked and repacked as a part of getting it ready for our first trip.... That's probably "to the extreme" for many people, very much a personal preference and certainly not a requirement....
