Knuckle Seal Design Change

The original 1st design knuckle seal design (left) is unshielded and was used from 1999 to early 2002.  A 2nd design, redesigned seal  with a shield on the inboard side (right) was introduced in late 2001 or early 2002.  The early seals will work on all 1999-2004 Super Duty's.  The later, shielded seal will only fit outer axles with a step diameter of approximately 3.115".  We have seen trucks all the way back to late 1999 with the 3.115" diameter step, but many trucks built prior to 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. Dan the Gear Man® Tech Note: Our new, QU40318 replacement outer axle shafts have the 3.115" step and can be used with either seal style.

Knuckle Seal Installation

Ford knuckle seals are 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 T1515 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.  Our T1515 Knuckle Seal Installer can be purchased separately from our Ford Tools page or 4x4tools.com
