Squealing noise from front of car
 

Hey guys,

I’m hoping someone has run into this problem and can help me. I’ve recently noticed a squealing/whistle sound coming from the front of my car. It only happens when I’m driving about 40 km/hr or higher then stops when I get below 40 km/hr. I thought it was a bearing issue but most mechanics are telling me it’s not. I decided to replace the front passenger bearing and it’s still making the same noise. Not sure if I should go and try and replace my driver side bearing... There’s still a lot of brake pads left just to rule that out as well.

I drive a 2009 Acura TL SHAWD and it has about 170k km on it.

Thanks all!

Sorry forgot to mention I also just changed the accessory belt and have tried revving the engine in idle but no sounds. Kinda sounds like metal brushing on metal causing the squeal.

- Most likely source of noise is the pulley on tension arm. I change mine every time I change the belt.
- Could be alternator. Mine made a squealing noise when it failed.
- Reverify that the belt is installed correctly.
- Turn AC off and if the squeal is still there that eliminates the AC compressor as the culprit.

Would it make noise in idle for the alternator? Cause mine doesn’t. It only makes a noise when driving.

Apparently my mechanic is now saying it’s the drive shaft. I do hear some noise coming from there when we spin the wheels... I hope it’s not the problem since those are apparently quite pricey.

I have a 2012 TL Elite and had the exact same whining noise.
It was the propeller shaft.

Thanks for the response! I’ve read on some other posts on this but want to be certain since it’s gonna cost me $1500 for the propeller shaft. Did it sound like it’s coming from the front of the car when windows are up? Is the propeller shaft is in the middle of the car? My mechanic said he heard it from the drive shaft front passenger side... is that the same thing?
