Parts for the Ford Expedition 99Q

Known issues

Some owners have reported the following issues with their Ford Expedition Base:
• Independent Rear Suspension (IRS) Bushings: The IRS bushings can wear out, particularly at higher mileage, leading to clunking noises or handling issues. This is often reported around 150,000-250,000 km.
• Spark Plug Ejection (5.4L Engine): Some Expeditions equipped with the 5.4L engine have experienced spark plug ejection issues. This typically occurs around 150,000-250,000 km. Periodic inspection of spark plugs and proper torqueing upon installation can help mitigate this.

WOF tips

During Warrant of Fitness (WoF) inspections, pay close attention to these areas:
• Suspension Components (Ball Joints, Bushings): Ensure all suspension components are in good condition and free from excessive play or wear.
• Brake Lines Corrosion: Inspect brake lines for any signs of corrosion, as this can compromise braking performance.

About the Ford Expedition 99Q

Here's what you should know as a Ford Expedition Base owner:

Maintenance Essentials:
• Engine Oil: Regular oil changes are crucial for engine health. Refer to your owner's manual for the recommended oil type and viscosity.
• Oil Filter: Change the oil filter with every oil change to ensure clean oil circulates throughout the engine.
• Fuel Filter: Replacing the fuel filter at the recommended intervals helps maintain optimal fuel delivery and engine performance.
• Drive Belt (CVT): Regularly inspect the drive belt (if equipped with a CVT) for wear and tear, and replace it as needed to prevent breakdowns.
• Wiper Blades (Front): Ensure good visibility by replacing worn wiper blades regularly.
• Disc Brake Rotor (Front): Monitor the condition of the front brake rotors and replace them when they reach the minimum thickness specification to ensure safe braking performance.
• Oxygen Sensor (Pre-Catalytic Converter): A faulty oxygen sensor can negatively affect fuel economy and emissions. If you notice any issues, have it inspected and potentially replaced.

Important Considerations for New Zealand Owners:
