About 15K miles ago I had a wheel bearing failure. I replaced the hub and bearings and put in a new seal. A few days ago I noticed it was leaking again, pretty badly, so I put in a new seal. Then I got to wondering if I was doing something wrong and that's why the first one failed. I know you are supposed to pack the bearings because the hub will be dry of oil for a while but are you supposed to do anything about the seal being dry? I put grease on it where it slides onto the shaft but, if I understand this seal, the part that rotates is in the middle, it does not rotate on the shaft. Are you supposed to somehow oil it up?

There may have been too much grease on the inner seal when you installed it or it may have gone on slightly crooked. I had to do the bearings too over the summer and it took forever to get the hub to go in straight. And yes, I k ow how to install races.

I always put some grease on the seal lip and on the axle where the seal runs. I'm an old school trucker, I squeeze 5 gts in the diff and then I drive, both ways, down a steep road bank to make sure plenty of lube gets to the bearings. I never have brg or seal problems.

Maybe it was just bad luck. It was a Timkin seal. I put an SKF in it this time.
