FAQs
Q1: Is this the left (driver) side or right (passenger) side hinge?
A: Please verify your specific vehicle before ordering. Left and right door hinges are typically not interchangeable. The OEM numbers listed (978520070, 6101410-803, 8978520070) may apply to one specific side. We recommend:
Checking your original hinge for a part number
Sending us a photo of your old hinge
Specifying left or right when ordering
Q2: How many door hinges does my truck have?
A: Each cab door has two hinges – an upper hinge and a lower hinge. For a complete vehicle (both doors), there are four hinges total.
Q3: What are the symptoms of a worn door hinge?
A: Common symptoms include door sag (door drops when opened), difficulty closing (must lift door to latch), door rubbing against fender or cab, uneven gaps between door and cab, wind noise, water leaks, and visible play when lifting the door edge.
Q4: Can I replace just one hinge on a door?
A: While technically possible, we strongly recommend replacing both hinges on a door at the same time. If one hinge is worn, the other has experienced similar wear and will likely fail soon. Replacing both ensures proper door alignment and saves labor costs.
Q5: Will this fit my Isuzu NPR71?
A: Yes. This door hinge is specifically designed for ISUZU NKR55, NKR77, and NPR71 series trucks. If your NPR71 uses factory door hinges, this is the correct replacement part (verify side compatibility).
Q6: What is the difference between OEM numbers 978520070, 6101410-803, and 8978520070?
A: These are different numbering formats for door hinges used on Isuzu N-Series trucks:
978520070 – Isuzu parts catalog format (older)
8978520070 / 8-97852007-0 / 8-97852-007-0 – Isuzu global parts catalog format
6101410-803 – Alternative parts catalog format
These numbers refer to door hinges for NKR55, NKR77, and NPR71. Please verify your original part number to ensure correct side.
