Put a thin bead of silicone around the tube where the seal sits and then install the new seal. I would also check to see if the rear shaft is bent. That is extreamly common with the 28 spline shafts and larger tires. You can put it on some jack stands and use a dial indicater to see if its out much.
Good time to upgrade to Moser or Dutchman shafts if it is bent.
