    Look on page 48 of the manual posted in post 1. Then using the description number like L68419 for Dexter part number 031-033-02 and Google you can find the Timken equivalent. 031-033-02 is on the build sheet in post #14.

      I think you just have to be prepared for a two day operation.
      Day1/ Jack it up and remove one hub. Remove seal.
      Hop in truck with previously removed seal and drive to commercial trailer service garage. Buy new seals that match what you removed earlier much cheaper than at RV dealer.
      Day2/ Do the bearing repack.
      Day2/ Afternoon. Open beer and admire your fine work.

        I've got 2 unopened packages of Genuine Dexter inner seals for D44 axles still in the double packs. Bought them for my previous 5er. Never replaced bearings just kept resetting end play till I dumped it.
