How to Correctly Position Oil/Grease Seal in Trailer Hub  

Question:

SORRY WHAT IS THE CORRECT POSITION OF FACES THE SEAL IN A HUB OF TRAYLER THANK

Expert Reply:

An oil seal like Redline part # 9103309 installs in the back side of the hub (the side nearest the trailer's frame) with the sides or "legs" of the seal inserted into the hub's bore. This means that the flat metal surface of the seal will face the trailer frame.

The linked photo of a seal will show you both sides and indicates the direction in which it should be installed into the hub.

I have linked both an article and video on seals that may be helpful to you.

Which way does the Timken seal go into the hub. One side has what looks like a small spring inside.

The open side where you can see the spring is the side that'll face towards the hub as you insert it into the bore. You'll follow the same procedure described above (and in the video I linked below) for your double lip seal.

@ChrisG Are you referring to the seal? It should still have markings/letters on it, and that would be the part that faces the frame.
