Decided I would clean and lube my wheel bearings. Purchased new grease seals from NAPA. Got the job done, and after a short trip to check everything out one of the BB's was flat indicating no grease. I checked the inside of the axle and found where the grease went. Bought a new grease seal and changed that one again and it made it to around 200 miles before it allowed the grease to leak out.

I've since purchased new seals from EZ Loader and intend to replace the bad one again this week. Any suggestions as to why only this one seal won't hold grease? I checked the axle and don't see anything out of the ordinary. Never an issue until I changed it. The other three seem fine. Appreciate some advice.
