Installation Notes
Installation steps (typical for front hub seal):
-
Safely lift vehicle and remove front wheels – support on jack stands.
-
Remove brake caliper and rotor (or drum) to access the hub.
-
Remove the hub assembly from the spindle.
-
Remove old inner seal – use a seal puller or pry bar carefully to avoid damaging hub bore.
-
Clean hub bore thoroughly – remove old sealant, rust, and debris. Inspect bore for scratches or burrs.
-
Inspect axle spindle – check for wear groove. If a groove is present (>0.5mm deep), install a Speedi-Sleeve or replace the spindle.
-
Lubrie new seal lips – apply a thin film of clean grease to the sealing lip.
-
Position new seal – place seal squarely into hub bore with lip facing inward (toward bearing cavity).
-
Drive seal evenly – use a seal driver that contacts the metal case (not the rubber lip). Tap gently until seal is flush or slightly recessed per OE spec.
-
Reinstall hub, bearings, and spindle nut – adjust bearing preload as per service manual.
-
Reinstall brake rotor/caliper and wheel.
-
Refill axle (if applicable) and test drive. Inspect for leaks after road test.
Quality Control
-
Material Verifiion: Rubber compound tested for hardness (Shore A 70-80), tensile strength, and oil swell (ASTM D471).
-
Dimensional Inspection: ID, OD, width, and lip geometry verified against OE blueprints.
-
Spring Tension Test: Garter spring force measured to ensure consistent lip radial load.
-
Leak Test (Dynamic): Sample seals tested on a rotating shaft simulator with hot oil to verify no leakage.
-
Visual Inspection: 100% checked for flash, cracks, missing spring, or case deformation.
-
Packaged Safely: Seals individually wrapped in plastic or sealed bags to prevent dust and ozone damage.
