Quality Control & Verification
QC Item Verification Method
Dimensional inspection CMM coordinate measurement against OEM drawing
Material composition Supplier material certificate / spectral analysis
Impact strength Drop weight impact test (per supplier report)
Weather resistance UV aging test (per supplier report)
Visual inspection Check for cracks, sink marks, flash
Packaging inspection Ensure no deformation or damage in transit
The above QC items are industry-standard recommendations. Actual QC standards should be based on supplier inspection reports. Bench test or third-party reports should be prioritized if available.
Installation & Maintenance Recommendations
⚠️ IMPORTANT: Confirm mounting side (LH/RH) and vehicle configuration before installation. Refer to ISUZU workshop manual.
Installation Guidelines

(Reference workshop manual):

  • Clean mounting area; inspect factory mounting holes for integrity
  • Align mud flap with mounting holes; hand-tighten bolts/clips
  • Tighten diagonally in sequence to OEM-specified torque (consult ISUZU workshop manual for specific torque values)
  • Check clearance between mud flap and tire to ensure no rubbing during operation
Maintenance Schedule:
  • Visual inspection of mud flap for cracks, deformation, or looseness at every service interval
  • Check fastener condition every 20,000–30,000 km or annually
  • Replace immediately upon crack, fracture, or loss
