Why does MY BMW make a whining noise when accelerating?
Diagnosing Whining Noise When Accelerating. For example, one of the reported reasons for whining noise in a BMW, was attributed to the noise created by the planetary gears. This is the kind of noise which is endemic to this automobile system. There are a range of car models and each one has its own peculiar issues.
What kind of noise does a car make during acceleration?
The most common noises cars make during acceleration is either a sucking wooshing sort of sound or a loud exhaust noise. The wooshing noise usually indicates that you’ve got a vacuum leak somewhere in your engine.
Why does my alternator make a whining noise?
Yes, it sure can! Your alternator has bearings inside that allows the pulley and stator to spin with the engine belt. If the belt is rubbing on the pulley due to misalignment or the bearings are worn out your alternator could indeed make a whining noise.
What kind of noise does a bad wheel bearing make?
If the noise is a little less if you turn right, the damaged bearing may be on the left, or vice versa. Note that tires that are “chopped” or “scalloped” (worn in patches) also make a rhythmic noise that increases in speed. This sounds very similar to a bad wheel bearing.

Why is differential noise most common on acceleration?
People talk about differential noise on acceleration because it’s the most common area where noise occurs from on acceleration. Reason is that the load on the gears makes it harder for the teeth to slide across each. This also increases load on the carrier bearings making them prone to failure also (and they too get really noisy).
Why does my steering wheel make a whooshing noise?
For one, If you are hearing whooshing noises, the most likely problem is a leaking vacuum system. But if it’s screeching noise, then you might be dealing with worn out brakes that need replacement. One, the steering fluid may be at a low level, in which case, the steering wheel makes noises as you turn it.
What to do when your car whines when you accelerate?
You could check whether the problem is in the transmission in the following way. Accelerate the car to speeds at which the whining noise is the loudest, switch to neutral gear and kill the engine. If the noise still persists, then the problem lies somewhere in the drivetrain or transmission.
What does it mean when you hear a whine in your car?
Back off about an inch from the lock position to ease the increase in pump pressure, and the noise should disappear. If you hear a constant whine, your pump is probably already damaged. Find out what it could mean if your steering wheel shakes. When you turn one way, you hear a clicking noise.

What causes a howling noise in the rear of a car?
Cause:Worn rear pinion bearing or worn gear set Noise:Howl without whir or rumble while accelerating at any speed (gears previously quiet) Cause:Worn gear set due to lack of lubrication or overloading Noise:Howling while accelerating over a small speed range (gears previously quiet) Cause:Worn gear set due to lack of lubrication or overloading
What does it mean when you hear a whining noise in your car?
What it means: If you have rear-wheel or four-wheel drive and hear this sound, the culprit could be the universal joint (U-joint), which are found in pairs and are components of the driveshaft. Get it checked by a mechanic immediately. 5. A howling, whining or even “singing”

What makes a car make a whirling noise when accelerating?
Cause: Loose pinion bearingpreload Noise: Howl with whir or rumble while accelerating at any speed (gears previously quiet) Cause:Worn rear pinion bearing or worn gear set Noise:Howl without whir or rumble while accelerating at any speed (gears previously quiet) Cause:Worn gear set due to lack of lubrication or overloading
What makes a humming noise at certain speeds?
The humming starts off with a lower tone (almost like a small plane flying overhead) and gets louder at certain speeds (35-40mph; 55-65 mph). I have switched to neutral and even turned off the engine momentarily(after ensuring it is safe on a lightly traveled road) to be sure that it is not from the engine.
When does a manual transmission make a whining noise?
A manual transmission is only turning when the car is either in motion, or when the transmission is in Neutral and the clutch is engaged (your foot is off the pedal). So sounds that occur while the car is stationary and in gear are most likely associated with the clutch.
What to do if your car makes a whining noise when not in gear?
Step 1: Ruling out engine noise. If the car doesn’t make the noise when it is not in gear, chances are it isn’t an engine noise. Race the engine gently with the car in Neutral and listen carefully for any signs of the offensive noise that are associated with the engine speed.
What to do about whiny noise from rear of Mercedes Benz?
I began by unbolting the drive shaft from the differential and secured it with a bungee out of the way. You do have to loosen the center driveshaft support to be able to push it far enough forward to get the centering sleeve off the locating alignment pin.
Why does my car make a whining noise when I crank the engine?
1. Freewheeling. You will feel this symptom when you crank the engine and you hear the whining noise mentioned earlier. This means the starter gear or pinion gear is not engaging the flywheel.
Why does my Mercedes Benz make a whiny noise in the rear?
(He has been on a mission!) It was now time to take the next step and change out the differential which is the most obvious culprit of the three moving components in the rear, ie, the differential and two axle shafts.
Why does my Silverado stereo make a whining noise?
It can tell you a lot about the health of your transmission. If your Silverado’s stereo is making a whining noise, it is usually caused by a condition known as “alternator whine”. Alternator whine is a product of a drop in voltage between the radio and the alternator itself.
Why is my rear differential making a whiny noise?
Having posted on Benzworld several times about an annoying whining noise coming from the rear, I finally got up the courage and replaced the rear Differential. Originally, I discounted the differential as being the source of the noise because I had not read a single post here or on any of the other forums of anyone replacing a differential.
Why does my car whine when I take a turn?
Power Steering Problems. If the whining noise while accelerating is loudest while taking a turn, the problem may lie in the power steering assembly. The main reason for the whining might be a loose belt, that runs over the power steering pump’s pulley.
What to do when your car makes a whining noise?
Shift the gear into the Neutral mode and crank the engine gently. If the noises seem to have a relation with the engine speed, the engine is in trouble. If there is no sound when the car is not in gear, the engine is unlikely to be the source of the complication. 5. The Clutch Components
Starting at approx. 3000 engine rpm, the alternator fan can cause a whining noise. At very low temp’s the alternator may whine for the first minute of operation. Check charging condition of battery. Recharge batter if necessary. If excessive magnet field whining still occurs: Replace alternator.
Why does my Ford Edge make a whining noise?
If it changes with the engine, it’s most likely going to be an accessory bolted to the engine (or the radio, shut it off and see if it stops). If it stay constant as you rev the engine it’s going to be something else. A whining sound when accelerating is almost always caused by a bad accessory attached to your Edge’s engine.

Where the sound is coming from exactly can be difficult to pinpoint. Try bouncing each corner of your car while your car is parked, or turning your steering wheel from lock to lock while stopped and listening for the sound. For a more in-depth procedure for diagnosing where your suspension problems are, check out our article about suspension noise.
