Car sounds too loud !

Hey guys so basic layout is my car sounds crazy loud inside and gets very loud at around 45mph+ . But for some reason when i steer to the left on the highway it dies down dramatically , and once steering wheel is back to center it sounds up again. Been like this since ive had it. Are there any reasons for this ? Ive heard it could be something with the exhaust but im not too sure?! Any ideas help , thanks!

I dont think the exhaust is affected by steering in any way. Power steering pump possibly...?? What kind of sound is it...

What's the condition of your heat shields and exhaust hangers? If one is loose your exhaust could be contacting the underside of the car and creating additional noise.

Nowhere near enough to go on. The skinny description of the symptom set makes me lean to the wheel bearings as a problem, or perhaps tire trouble. When you turn the steering wheel, you alter the weight and balance of the car, this makes the noise go away and return. I put this sort of thing on wheel bearings and/or tires.

I like this diagnosis. You do not tell us what the sound is, a heat shield would produce a rattling noise, the tires/bearings would make a rubbing/pulsating noise as the affected area goes around and around.

Your description is exactly how it was for me when one of my rear bearings went out.

Should also check your cooling fan. The fan can get loud before it goes off like a grenade and destroys a bunch of stuff under your hood.

if its sounds like this then its one or 2 of your bearings, I think you mention that when you turn it seems to calm down. Now that I remember that is what my E36 was doing and it was my one of my rear bearings.

I replace both of them and I was good 2 go.

Mine had a speed sensitive droaning sound. Thought it was the bearings. Turned out to be just the lousy Goodyears. I replaced it w/ some Michellins and all is well again. It was loud though since the tires still had a ton of thread life left. They were just badly cupped.

Smart money would be wondering why the tires had a ton of tread left, but were badly cupped. This indicates suspension issues that will soon make the new tires be cupped also.

But, yes. Road noises that change when the load on the car changes points to the tires and/or bearings.

Hey guys took a video last night and you kind of have to put it next to your ear if you have mobile. Really hopes this helps narrow it down.

I'm sticking with the wheel bearing somewhere. Having said that, the diff is an option. The center support bearing. You have said that the noise changes when you turn, this says that the load on the tires changes, which brings us back to the wheel bearings.
