'77 Trailer Bearings

Sounds to me like a bad inner seal. I recommend you attach the trailer to a vehicle while jacking it up to keep it from spinning and dropping on you. Pull the cap and then take apart what you see and tell us what you find. Its very similar to the bike bearings, but the bearings are not loose and should not spill out everywhere unless they are completely toast.

There is likely a broken spring on the inside of the seal. Mine were broke both sides so I had to replace them. I noticed that the bore of the hub will allow you to press the seals in too far, so be careful when driving them in.

Watch a video on how to pack wheel bearings with your hand. The grease must be pushed thru the tapered roller bearings and cage. You can't just roll it around in grease.

Look at the spindle surface where the seal rides. If it has ANY pitting that won't clean up, the solution is to install a Speedi-Sleeve.

Pete, U the man

I've had the same problem since I bought our 81 SN back when. One wheel slings grease on the backside and the other is clean. The clean side has a sleeve on it. MidWest said CC never put these on the axles and had no explanation why one side was sleeved and the other not. Nor did they have any idea where I could buy one. I knew the sleeve was tightening the seal but never seen one used on an axle before. After looking for a few years, I gave up trying to fix it and simply clean up the mess when I do the bearings.   The axles don't show any signs of wear in the sealing area so maybe they are somehow slightly undersized? Now to see if I can find one before bearing cleaning time.

Thanks
