If your Ford Expedition is making a whining noise, it’s most likely due to something in the engine area. When and under what conditions you hear the whining noise will determine the most likely source.
Your car’s transmission is in charge of getting it moving by transferring power from the engine to the wheels. You may almost certainly hear some noise; however, if it starts making strange noises, such as a whining noise when in gear, it’s a sign that something is amiss. The problem could be determining what it is.
Is the whining consistent when you crank the engine before going any further? Or does it remain constant regardless of engine speed? It’ll most likely be an accessory bolted to the engine if it changes with the engine. It’ll be something else if it stays steady when you crank the engine.

Common causes of Ford expedition whining noise when accelerating
A bad accessory attached to your Expedition’s engine is almost always the cause of a whining sound when accelerating. The most typical reasons for whining noises when accelerating are as follows:
1. Alternator failure
When an alternator starts to fail, it will often emit a high-pitched whining sound. It should also have a battery light attached to it. If not, it’s possible that your Expedition’s whine isn’t caused by the alternator, though this can’t be ruled out completely.
2. Steering assist
The power steering pump is a common cause of whining when your Ford Expedition accelerates. They’ll make it whine a lot if it gets too low on fluid. Check the fluid level and refill to the factory fill line if necessary.
The pump may also fail. Turn the steering wheel left and right while the vehicle is parked to see whether it’s the power steering pump. Is it true that the sound gets louder as you turn? That’s a strong indicator that the noise is coming from the power steering pump. Depending on the RPM, all of your engine accessories will change color. Only the power steering pump is affected by RPM or steering wheel movement.
3. Serpentine Belt That Has Been Worn
The serpentine belt on your Expedition is in charge of taking the motion from the crankshaft and using it to turn all of your accessories. When it breaks down, it emits a high-pitched whine. That is especially true when the car is first started. More on this can be found below under the whines while starting the section.
4. Operation as usual
Some transmissions, as previously said, have an inherent whine that is quite natural. Depending on the make and model, the whining may be most perceptible in first gear, third gear, or another gear. The best defense is to be aware of how your transmission generally sounds.
5. There is a shortage of transmission fluid
Low transmission fluid is the primary source of whining when in gear in manual and automatic gearboxes. The transmission’s internal components will not be adequately lubricated if the fluid level is too low. Friction between those pieces is causing the noise you’re hearing, and it can cause serious damage. It’s a good idea to check for transmission fluid leaks if the fluid level is low.

6. Wheel Bearing Failure
Although wheel bearings are found in each wheel hub, the sound might travel and appear to originate from the transmission. While a deteriorating wheel bearing is more likely to make a roaring noise, it is also conceivable to make a whine while driving.
On the other hand, if you notice that the more you accelerate, the louder your Ford Expedition’s noise at acceleration becomes, you should consider your vehicle’s rolling parts. If the loud noise persists while you idle, it is almost probably related to your movement and, more broadly, the wheels. The fundamental cause is the condition of your bearings; therefore, ensure they’re in good shape before assuming that’s what’s causing the noises as you accelerate.
7. Pumping Water
When a water pump breaks down, it makes a squeaky noise. A faulty alternator will usually sound like a deeper whine.
8. The turbo makes a rattling or whistling noise
When you accelerate your Ford Expedition and notice a decrease of power along with a rattling noise, the turbo may be deteriorating, and most of the parts have reached the end of their useful life. Examine and replace the turbo if it is the source of the problem; otherwise, your engine may become clogged. When you hear a blowing or whistling sound coming from your vehicle, read this document regarding turbo noises on Ford Expedition for more information.
9. Air leaking causes a humming noise
If you don’t notice any power loss while your Ford Expedition makes a humming noise, one of your connections or air hoses is most likely leaking. So look over your complete air supply system, from the air filter to the engine, to figure out where the acceleration sound is coming from.
Solutions to the Ford expedition whining noise when accelerating
On the other hand, if you notice that the more you accelerate, the louder your Ford Expedition’s noise at acceleration, you should consider your vehicle’s rolling parts.

The fundamental cause is the condition of your bearings; therefore, ensure they’re in good shape before assuming that’s what’s causing the noises as you accelerate.
If your Ford Expedition produces a loud noise while you accelerate, the problem may be caused by the alternator belt. You’ll need to figure out if this noise occurs suddenly or if it can be stopped. Although it is less critical than the timing belt, the alternator belt is a worn element that supplies power to the secondary components of your Ford Expedition’s engine.
If it breaks, it can cause engine failure. This noise could indicate a slackened belt, in which case the tensioner roller or its wear and tear could be blamed. In any event, inspect the condition and tension of your belt. If your Ford Expedition makes this acceleration noise, take it to your mechanic.
Finally, if the noise accelerates with your Ford Expedition, and the noise goes away when you disengage, one of your clutch system’s wear parts could be to blame. You are supposed to replace the clutch release bearings every 120 000 to 130 000 kilometers.
To test it, see if shifting gears is more difficult than usual and if you sense a stronger or non-existent resistance in the clutch pedal. When you see any of these signs, take your Ford Expedition to a professional to replace the clutch release bearings.
When you hear unusual noises in your Ford Expedition, you’re likely to be concerned. Especially if your Ford Expedition makes a noise when you speed. It’s immediately linked to an engine motor problem, and as a result, it’s potentially dangerous.
There are various reasons why you might hear a whining sound when accelerating in your Ford Expedition, including low steering fluid levels or a failing or leaking steering pump, as discussed above in this article.
Heck, it might be the alternator, worn belts, or any number of other things; this is the common cold of automobiles. Fortunately or unfortunately, the rear differential is the rear differential, the most typical cause of this whine on the Expedition, depending on whether having a known failure counts as a good thing, especially if it reveals itself between 42 and 65 miles per hour. If your automobile is still under warranty, there will be no charge, but otherwise, expect to spend between $200 and $400, including labor.
