What is wrong with my car?

Belt or bearing

there are several items running that can produce a noise
the water pump bearing will be a grumble or a tinny rattle , the idler pulleys will be a rattle, the ac pulley is on a bearing separate to the ac operation and is running all the time and the problem noise could be from that bearing
the alternator bearing will make a medium pitch rumble and if you have a viscous ( clutch hub) fan hub the bearings in it will produce a noise
an accredited mechanical shop will have a stethoscope and a good mechanic will be able to determine exactly where the noise is coming from

Best Manuals I used their book once back in 2012, I still used it.. It's been so helpful

if, there no marks on rotors and they wareing off evenly ,no need to be change,the sound when you press the brakes its could be cause by cheap brake pads.dont get me wrong ,that depent on the market brand of the brake pads ,seem that who did your brake job didnt use a good brake pads.they will need to be change to avoid the noise.good luck

the defroster makes the ac compressur kick on

check the spark plug confi they might be wired wrong

Make sure you check your power steering fluid... if it's even low, it will make a terrible noise...run it on empty too long and your can ruin your power steering pump.

Good Day,
It would make sense that it is suspension related as it does not make noise at idle but going down the road it does. I would lean towards it being a bad wheel bearing. Does it sound like it's coming from one side or the other? Also how many miles on the car? Does it get louder when the wheels are turning?

You can check the bearing easily by jacking up that wheel and moving it side to side and up down checking for play, a little bit of play is normal.

Hope this helps and Good Luck
