99-05 Ford Excursion And Super Duty Knuckle Seal And Tool Kit

QK4610 Type 1 Super Duty Knuckle Seal Kit includes our heavy-duty QT1515 Knuckle Seal Installer, plus 2 each QU40233 Unshielded Knuckle Seals, QU20023 wheel hub-to-knuckle O-Rings and QU20044 lockout hub O-Rings. Seal replacement is required anytime the axle shaft is removed to prevent vacuum leaks and or water infiltration. Use the QT1515 for damage free installation of the knuckle seal on the outer axle shaft and then use it to seat the axle shaft assembly in the knuckle to the proper depth. This Kit is specific to 1999-2002 Ford Super Duty® and 2000-2002 Ford Excursion Front Axles but will work on 2003-2004 Super Duty® and 2003-2005 Excursion models also.

Tech Note 1: Design Change
(About Knuckle Seal Design Change) This unshielded Seal is the original 1st knuckle seal design that was used from 1999 to early 2002. A 2nd design, (QU20035) redesigned seal with a metal deflector shield on the inboard side was introduced in 2002 calendar year as a 2003 model year part. The early QU40233 seals will work on all 1999-2004 Super Duty's. The later, QU20035 shielded seal will only fit outer axles with a step diameter of approximately 3.115". Most Trucks built prior to mid 2002 will have outer shafts with a step diameter of 3.210" which will not accept the shielded seal. We recommend you order replacement seals that match the seal type your truck originally came with. Our new, QU40318 series replacement outer axle shafts have the 3.115" step and can be used with either seal style.

Tech Note 2: Installation
(About Knuckle Seal Installation) Ford Excursion and 1999 to 2004 Ford Super Duty® axle shaft to knuckle seals are just about the toughest seals to install we have ever come across. The seal is of a complicated unitized design that is easily damaged without the correct installer. In fact, the knuckle seal is virtually impossible to install without damage unless a tool like our one piece, rugged 12 pound QT1515 Knuckle Seal Installer is used to drive or press the seal on. Not only is the seal an extremely tight fit to the shaft, it also must be installed to a specific depth on both the axle shaft and in the knuckle. A damaged seal will allow water to enter and vacuum to escape.
