Tech Note 1: Interchangeable
This seal is interchangeable with our QU50075 special double lip seal.

Tech Note 2: Use Proper Tools
Wheel Seals are easily damaged when using makeshift installation tools. Use QT1512 Seal Installer for 1972 to 1993 trucks or QT1538 for 1994 to 2002 models along with our QT1100 1" x 8" Standard Installer Driver Handle or QT1116 1.25" x 8" Pro Duty Driver Handle.

Tech Note 3: Before Installing
Always lubricate the lip of your new seal with clean grease before installing the hub on the spindle!

Tech Note 4: Common Causes of Leaks
Many wheel seal leaks are caused by pressure building in axle due to a clogged axle vent system. Always check and clear the vent system. Other common causes of leaking seals include improper wheel bearing adjustment (See TSB4008), poor installation techniques (See Tech Notes 2 and 3 above), and worn spindle surface.
