When installing a seal at the back of a hub the outer part of the seal will need to be flush with the hub. I have linked a video that should help. You could watch the whole video or fast forward to the 1 minute, 50 second mark to see the seal installation.

My replacement grease seals (for my boat trailer) are half the thickness (0.25") of the old one (0.437"). If I install the new grease seal in so that it is flush with the back side of the hub, I think there will be some play allowing the bearing to partially come out of the race. Can I still use these new thinner grease seals if I install them further into the hub?
