2018-2024 Expedition & Navigator Tailgate Hinge: Diagnosing Noise, Binding, and Alignment Issues

Symptoms of a Failing Tailgate Hinge

While widespread catastrophic failure of the tailgate hinges on the 2018-2024 Ford Expedition and Lincoln Navigator is not common, wear and tear can lead to noticeable issues. Most problems are related to noise, movement, and alignment rather than the hinge physically breaking.

• Popping or Creaking Noises: A loud pop, creak, or groan when opening or closing the liftgate is a primary symptom. This sound is often caused by wear in the hinge's pivot point, lack of lubrication, or metal-on-metal contact due to wear.
• Binding or Resistance: The tailgate may feel unusually heavy or seem to catch at a certain point during its travel. For vehicles with a power liftgate, a binding hinge can strain the motor, causing it to struggle, stop mid-travel, or reverse direction unexpectedly.
• Tailgate Misalignment: A worn hinge can allow the tailgate to sag. You can spot this by looking at the body lines and panel gaps between the tailgate and the rear quarter panels. The gap may be uneven, or one side of the tailgate may sit lower or stick out further than the other.
• Difficulty Latching: Severe misalignment can prevent the tailgate from latching securely, which may trigger a "Liftgate Ajar" warning on the dashboard.

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

As of mid-2024, there are no specific safety recalls or Technical Service Bulletins (TSBs) from Ford or the NHTSA for the main tailgate hinges on the 2018-2024 Ford Expedition and Lincoln Navigator.

These vehicles have been subject to other recalls for issues like seat belt pretensioners and transmission components, but the hinges themselves have not been identified as a widespread safety defect. Problems with the hinges are generally considered a wear-and-tear item addressed on a case-by-case basis.

It is important to distinguish hinge issues from other common liftgate problems discussed by owners, such as:

• Power liftgate motor failure.
• Electrical faults causing the liftgate to open on its own.
• Failure of the separate, smaller hinges for the opening rear glass.

Buying a Used Tailgate Hinge for Your Expedition or Navigator

When replacing a tailgate hinge on these vehicles, a high-quality used OEM part is often the best value. As of now, there are no widely available aftermarket replacements for the main tailgate hinges, making your choices new OEM or used OEM.

Why Choose a Used OEM Hinge?

Original Equipment Manufacturer (OEM) hinges are designed by Ford to meet the exact specifications for fit, durability, and material strength required to support the heavy tailgate. A used OEM hinge from a lower-mileage vehicle offers the same factory fit and quality at a significant discount compared to a new part from a dealer.

Pre-Purchase Inspection Checklist

Before buying a used hinge, inspect it carefully for the following:

• Check the Pivot Point: Hold both halves of the hinge and try to wiggle them. There should be minimal to no play or looseness in the pivot pin. Excessive play is a sign of wear and will cause sagging.
• Inspect for Cracks: Closely examine the hinge body, especially around the mounting holes and the pivot area, for any hairline cracks in the metal.
• Verify Straightness: Lay the hinge on a flat surface. It should sit flat without any rocking. A bent or twisted hinge will make alignment impossible and may indicate it came from a vehicle involved in a collision.
• Confirm the Correct Side: Hinges are side-specific. Part number JL1Z-7842900-A is for the right (passenger) side, and JL1Z-7842901-A is for the left (driver) side. Ensure you are buying the correct one for your needs.

Replacement Overview & Difficulty

• Difficulty: 4 out of 5
• Estimated Time: 2-3 hours
• DIY Feasible: Yes, for experienced DIYers with a helper.

Replacing a tailgate hinge is a challenging job primarily because the liftgate is extremely heavy and bulky. This is a two-person job for safety. Attempting this alone can result in injury or damage to the vehicle.

High-Level Replacement Steps:

1. Support the Tailgate: With the tailgate open, you MUST support its full weight. Use a transmission jack, padded jack stands, or have a strong helper hold it securely throughout the entire process.
2. Disconnect Components: Disconnect the gas-charged lift supports. You will also need to access and disconnect any electrical wiring harnesses that run from the body into the tailgate for the lights, camera, and power latch.
3. Remove Interior Trim: To access the nuts securing the hinges to the body, you will likely need to remove the upper D-pillar trim panels and possibly part of the headliner inside the cargo area.
4. Unbolt the Hinges: With the tailgate supported, have a helper hold it steady while you unbolt the old hinge(s) from both the body and the tailgate itself.
5. Install New Hinges: Loosely bolt the new hinge(s) in place.
6. Align and Torque: This is the most critical step. With the new hinges loosely attached, carefully adjust the tailgate to achieve even panel gaps on all sides. Once aligned, tighten the bolts to the manufacturer's specification. A general torque value for similar applications is 26-34 Nm (19-25 lb-ft) for hinge-to-body bolts and 7-10 Nm (5-7 lb-ft) for hinge-to-tailgate bolts, but always refer to a specific service manual for your vehicle.
7. Reassemble: Reconnect the lift supports and electrical harnesses, then reinstall all interior trim panels. Test the tailgate's operation, both manually and with the power function if equipped.

Cost to Replace a Tailgate Hinge
