Front wheel bearings repair?

The OEM hubs are similar but not the same.

Where does the dirty grease go when you inject grease thru the sensor hole? Seems like a less than ideal situation.

I believe the term "sealed" refers to the entire assy., not the bearings within the hub housing. Puttin' lube in there would be identical to adding grease to a boat trailer hub, centrifugal force forces it out to wherever it can go.

So it is, and to much grease comes out at the inside of the hub at the seal.
