Is There An Issue With Seating Grease Seal Slightly Below Hub Face?

Question:

Hi. When installing the grease seal in an easy-lube hub/drum, what could be the consequences of pressing the hub seal below flush to its stop at the bottom of the seal bore versus pressing the seal flush with hub as specified? It appears the difference in depth is about 1/16inch inch. Will the seal still do its job if pressed below flush? Thanks!

There is not an issue with installing the grease seal # 9103309 you were looking at 1/16" below the face of the hub. It will still seal against the grease seal surface on your axle, though you will want to make sure to not force the seal down to far as you can press it down against the bearing and race and cause issues there.

I included a video showing the grease seal, inner bearing and race, and outer bearing and race being installed on on a hub for you to take a look at.
