Despite its strengths, the 1998 Ford Expedition is known for experiencing several issues.

Engine

4.6L V8

• Spark Plug Failure: Premature wear or loosening of spark plugs leads to misfiring, rough idling, and decreased engine performance. Requires replacement of spark plugs and ignition coils. $200 - $500+

• Intake Manifold Gasket Failure: Gasket failure can cause vacuum leaks, resulting in poor engine performance, rough idling, and increased fuel consumption. Requires removal and replacement of the intake manifold. $500 - $1,000+

5.4L V8

• Cam Phasor Failure: Failure of camshaft timing components can lead to decreased engine power, rough idling, and engine damage. Replacement of cam phasors and associated components is required. $2,000 - $3,000+

Transmission

4-speed Automatic

• Torque Converter Shudder: Vibration or shaking during acceleration is caused by a faulty torque converter. Requires removal and replacement of the torque converter. $1,000 - $2,000+

5-speed Automatic

• Harsh Shifting: Rough or delayed gear changes indicate a problem with the transmission control module or transmission hydraulics. Diagnostic testing and repair or replacement of affected components is necessary. $500 - $2,000+

Suspension

• Leaking Struts: Worn strut seals lead to fluid leakage and reduced ride quality. Replacement of struts is required. $500 - $1,000+ per axle

• Ball Joint Failure: Loose or worn ball joints can cause unstable handling, pulling, and tire wear. Replacement of ball joints is necessary. $200 - $500+ per joint

Electrical

• Instrument Cluster Failure: Malfunctioning components can lead to inoperable gauges or incorrect readings. Replacement of the instrument cluster is required. $300 - $700+

• Headlight Switch Failure: Intermittent or unresponsive headlights can be caused by a faulty switch. Replacement of the headlight switch is necessary. $100 - $300+

Exterior

• Tailgate Handle Failure: Broken or malfunctioning tailgate handles impede access to the cargo area. Replacement of the tailgate handle is required. $100 - $300+

• Door Lock Actuator Failure: Inoperable door locks are often caused by failed actuators. Replacement of door lock actuators is necessary. $200 - $500+ per door

Interior

• Dashboard Cracking: Exposure to sunlight can cause the dashboard to crack and deteriorate over time. Repair or replacement of the dashboard is necessary. $500 - $1,500+

• Rear Seat Release Failure: Broken or jammed rear seat release handles prevent access to the third row of seats. Replacement of the rear seat release handles is required. $100 - $300+

Summary:

The 1998 Ford Expedition is a capable SUV but has a history of potential issues in various components. The most severe and costly problems include cam phasor failure in the 5.4L V8 engine, which can require significant repairs, and instrument cluster failure. Other issues, such as suspension leaks and dashboard cracking, are more common but less costly to address. Prospective buyers should be aware of these potential issues and consider their impact on ownership costs.
