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.

I believe I was able to find the bearings and seals that you need, but you'll want to double check on your end by removing the hub and looking at part numbers just to make sure. Inner Bearing - #25580 Inner Race - #25520 Outer Bearing - #02475…

Yes, there is a difference between an oil seal and a grease seal for trailer hubs. Oil seals have a much tighter fit on the spindle to keep the oil from leaking out. An oil seal can be used with grease but a grease seal cannot be used with oil. The…

Brake magnet clips attach the brake magnet to the brake assembly so they should still be on there when you take the drum off. I looked up the 10,000lbs Dexter axle and the #BP19005 is the correct part for the 12 inch electric brake assembles oval…

Answer 10

The magnet clips #BP19005 should not be making contact with the drum while the brakes engage, so I do not think that is the problem. What I think is going on is it's just not seating all the way. These can get a little squished or deformed…
