Stemco wheel seals

I an going axle by axle and fixing all the dumb stuff that gets missed or half assed by half a lifetime worth of company driver-ness. With the availability of the SKF, it sounds like that's the way to go. All 3 axles are getting new wheel bearings and pro torque nuts as well so I can dial the end play in better and to increase seal life and lessen drag. Just wanted to make sure I wasn't leaving something on the table with the seals.

Your doing exactly what I did to my trailer about 5-6years ago, when I rebuilt my trailer 2 years ago only one wheel seal had been changed in the 3-4 previous years. Keep in mind I barely ran 100k miles/year and 4 of the 6 trailer axles spend half their life being hauled around stacked up, to give you an example of life expectancy. Also the loaded miles, are ALL permitted weight, from 38-45k lbs/tandem, so definable weight used but not speed abused.
When I did this, I also installed Tru-Balance wheel centering devices and Centrimatic balances at the same time. The increased tire life from doing all of the above paid double the investment of the parts! That was ~2 sets of tires ago, easy money!
With all of that done with synthetic 75/90 oil in the hubs, my hub temps dropped 10-15 degrees (iirc working on memory). But the best part was all 12 wheel ends (6 axles) on the trailer were within about 7*f hottest to coolest! Using my infared gun. I wouldn't believe it if I didn't see it myself. I was anal, and because of the accuracy of the ProTorq nuts I set every single hub at 0.003".
