i would make sure the bearing has plenty of grease in there, you can't really put to much in like that one guy said, make sure its well covered.

thanks.
that is just what i wanted to hear.
if all these bearings come this way, its no wonder they have such a short life, they would run dry in no-time.
that plus the way the wheel is cantilevered out loading the bearing in kind of a bearing mode rather than radially...

They are sealed bearings. You should not be reusing sealed bearings if they come apart. Greasing them won't help. Replace it!

yeah, i know. I guess i should have been more clear.
it was the NEW bearings that i was preparing to install that had hardly any grease in them. the old ones were shot, thats why i was replacing them...

i dont see how these could live very long with that little lube in there

Because they are sealed. I hope you didn't install those after you took them apart.

you bet your sweet **** i did
i dont see how i could have ruined anything by taking them apart. they are not held together by anything other than the seals, and they were easily finessed out of place.
these are not what i would typically think of when i think of sealed bearings, those are indeed practically impossible to get apart without destroying. these guys would fall apart if you dropped one on the ground.
Like i said earlier i dont know if that grease in there is supposed to be magical, but if you packed some old school tapered roller bearings with only that small amount of grease, they would be toast in no time..
I guess I will be my own personal guinea pig for this one, but from what it sounds like its not uncommon for these bearings to have irregulary short life i would rather not go through this again any time soon

Exactly. They are sealed bearings. Taking them apart ruins the seals. Additionally, from the looks of it, there's some orange rust in there now.

All sealed bearings are like that. They are standardized and only a few companies actually manufacture them.

Selaed bearings do not require as much grease as re-packable bearings because they are supposed to be sealed. The largest issue with sealed bearings is that they cannot sustain a shock. Pot holes are usually the biggest factor in reducing a sealed bearing's service life. Most FWD and AWD vehicles using sealed bearings need new bearings around 120k miles. This has been the case ever since the birth of the sealed bearing, but re-packable bearings require service every 30k miles or so. In the end, it's all about the same.

Keep your fingers crossed you haven't shortened the bearing's life considerably by compromising it's seal. Other than flat-spotted ***** or broken cages from pot holes, the next leading cause of failed wheel bearings I've seen is due to rust and dirt due to a failed seal.
