How do Bearings and Hub Seals Install on a Boat Trailer Hub

Question

Question:

Hi guys, I bought your spindle seal kits for my boat trailer. Do I understand that the large inner bearing sits on top of the rubber O-ring? How is that O-ring going to hold up under that bearing ? Maybe Im missing something ? Thank you,

Expert Reply:

The inner bearing will not ride on the rubber o-ring. The bearing will ride on the spindle and the seal goes just to the outside of it and keeps the grease from leaking out of the hub.

To see how it all goes together check out the video I attached.
