Why is my car loud when I let off the gas?

It can be an indication of an extremely worn bushing. Do not ignore a car that thuds when taking the foot off the accelerator pedal. Have an auto mechanic perform a vehicle inspection to determine why your car makes a knocking sound when letting off the gas pedal.

What makes a loud roaring noise when accelerating?

Took my warrantied vehicle listed above (v8 premier) in to have the radiator fixed and when I got the car back it had an extremely loud roaring noise when accelerating. I took it back in and they replaced the electronic fan clutch but it is still making the noise.

When does the engine roaring increase with speed?

It sounds like the entire front end is going to blow off, it is so loud. It is loudest when initially accelerating from a stop. If I increase speed from level speed, it either does not make the noise, which sounds like a loud roaring, or it is not as loud.

Why does my car make a loud noise when I increase speed?

If I increase speed from level speed, it either does not make the noise, which sounds like a loud roaring, or it is not as loud. Previously, the only time my car made any kind of “odd” or louder noise would be the first time I turned it on after not driving it for awhile, but it would stop within a minute or so.

What causes a low pitch noise when accelerating?

Noise:Howling while accelerating over a small speed range (gears previously quiet) Cause:Worn gear set due to lack of lubrication or overloading Noise:Howling after gear set installation Cause:Faulty gears or improper installation Noise:Low-pitch rumble at all speeds over 20 miles per hour Cause:Worn carrier bearings

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

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).
