ISUZU NPR NKR77 Front Hub Oil Seal 8-94248117-1 8942481171 OEM Fit
Product Overview
Front Hub Oil Seal 8-94248117-1 8942481171 is a verified direct-fit replacement for ISUZU NPR / NQR / NKR / NKR77 / NLR / NMR / 100P / 600P / 700P light and medium-duty trucks equipped with 4JH1 / 4HK1 / 4HF1 / 4HG1 / 4HE1 diesel engines. This critical wheel hub sealing component retains hub lubrication and prevents dirt, water, and debris from entering the wheel bearing assembly.
Working Principle
The front hub oil seal creates a dynamic seal between the rotating hub and stationary axle spindle. The dual-lip design features a primary sealing lip that maintains contact under spring tension and a secondary dust lip that blocks contaminants. Constructed with steel-cased, rubber-covered construction for secure press-fit installation.
Failure Symptoms
Grease leakage at the wheel hub - visible grease traces on inner wheel or brake backing plate
Wheel bearing noise or vibration - growling or rumbling noises from bearing wear
Brake contamination - grease leaking past failed seal reduces braking effectiveness
Water or mud intrusion - contaminants cause rust and pitting on bearing surfaces
Excessive wheel bearing play - detectable wheel play from bearing degradation
ISUZU service manuals require that the front hub oil seal be replaced, never reused whenever the wheel hub is removed. Always replace both left and right seals simultaneously.
Fitment Notes: This oil seal is designed for 73×90×8 mm applications. Verify dimensions before ordering. Replace in pairs (both sides of front axle). For RHD vehicles, verify clearance and orientation.

Verify smooth rotation and perform road test
Maintenance Schedule
