Really bad sound
ok so something somewhere in my car is causing it to make this really bad squeaking sound as if you had wet shoes on a basketball court and its not the brakes and i think its coming from the transmission because it gets louder and faster as the rpms climb and after around 4k it goes silent, or after i hit a certain speed. also it only happens at night and i have no idea how to create the sound. any idea on this?
i have a 10th anniversary miata with 90k miles |
I really wish that last sentence hadn't have been there.
This is classic speedometer cable whine. Except that NBs don't have speedometer cables. Since you said it's not the brakes, I assume that you completely removed all 8 brake pads from the four corners of the car, drove the pistons fully back into the calipers, and went for a test drive with no brakes at all. Since it only happens at night, and you indicate no correlation to the phase of the moon, I conclude that you are being stalked by a vampire. Garlic-flavored bubble gum is available from several sources, and is generally understood to repel vampires. (also, replace your alternator belt.) |
ok well i assume its not the brakes because it still whines slightly when the car is parked.
hmm not sure about the vampires, could be zombies though |
Belts are the first thing to check. After that, I'd assume idler on the timing belt.
Does the sound change if you ride the clutch a little? That's throwout bearing. |
The sound will slow down when i ride the clutch but gets louder as i speed up, if i throw the car in neutral and roll for a while it still leaves a faint whistle
|
So, this squealing sound:
Here's a riddle: What makes a squealing noise under the hood which rises with RPM, is affected by changes in electrical load (such as operating the headlights, which is something I assume you do at night), and is shaped like an alternator belt? |
Cat stuck in the pulleys?

Harbor Freight stethoscope.....hit the alternator and water pump.....but I think Joe hit it on the head, check your belt! I will be in Monroe tomorrow afternoon if you want me to have a look see PM me.

This caused the entropy of the cat to increase significantly. |
