Dan the Gear Man® Tech Notes:

To Install
2017-current Installation Spacer
Applications
Tech Note 1: Must Replace
Seal, Gasket, and O-Ring replacement is required anytime the axle shaft is removed to prevent vacuum leaks and or water infiltration.
Tech Note 2: To Install
2005 and newer Ford F250 to F550 Super Duty® axle shaft to knuckle seals are of a complicated unitized design that is easily damaged without the correct installer. To function with any longevity, QU20052 Seal must be installed with TS1530 (F250, F350) or TS1531 (F450, F550) Installer to a specific depth on both the axle shaft and in the knuckle. An improperly installed or damaged seal will allow water to enter and vacuum to escape.
Tech Note 3: 2017-current Installation Spacer
2017 and newer Super Duty also requires QT1551 Installation Spacer be placed between QU20052 Seal and QT1531 Installer Head which will seat the Seal approximately 0.030" deeper in the Knuckle as called for in 2017 and newer Ford Service Manuals.
