My Mercedes C55 made the same noise. It was alternator bearing. Noise is similar to power steering. The difference is alternator noise changes pitch with engine revs while power steering noise changes with application of steering lock. Be careful with "re-man" alternators which sometimes have cheap regulators installed. I got an OEM from the junkyard and transferred my low miles regulator over. Noise gone.

Thank you! Now I know it’s my alternator. I thought my problem was the transmission. The alternator it’s much cheaper to replace.

Same problem on my Celica 2005... I did the same. I changed the power steering fluid but the noise didn't disappear. The real problem was the alternator. Thanks for your video.

Just happened to me all of a sudden, sounded like a mean twin turbo on my truck 🤣

This is the only video about this that i can find, my honda civic has the same sound and i kept thinking it was the power steering.

This shit scared the hell out of me on my bmw, I was like “this it, no more bmw”

[kingxyotti]

very helpful, thought that was my power steering till my car died in the road. finna go get a new one

[JohnPaluska]

Well, thank you for confirming what I thought. My car has the same ticking noise. New battery was put in today and I had one almost failed start. I guess it's time for a new alternator.

[BradBrother]

Thanks for posing! I always thought a whining sound was power steering. I'm suspecting alternator is on it's way out. I think if you unplug the alternator, and if it stops making that sound, it's for sure that.

Now it makes sense why that one car drive by sounding like a spaceship

You might want to check your ac compressor bearing, basically the ac clutch.

Dude you just made my life sooo much easier! Thanks so much! Good bless

[Craigonater]

Yep. That's what it sounds like. Lol. My Torrent sounds just like that and I've been putting off changing it until today. I finally got the service charging system warning this morning on my way to work. 😥

I’m telling every one it’s my alternator but no one believes me 😭

[Godisgralways]

Tap the alternator once or twice and you should be good to go I’m not sure for how long though but it should work. With a hammer. Don’t take my word for it though. Watched a video on YouTube

[mrkc]

I just had this problem. what exactly did you replace? Freewheel or rear carbon electronics?

[seth]

Thanks for the video! This is exactly what happened to my car. Thought it was the power steering.

Any input on my situation? I have a 2014 outback and recently got the short block rebuilt on a recall. They pulled the motor and it took roughly 5 weeks to get it back. My alternator was incredibly loud like this video but withing 2 weeks of driving the sound died down ALOT. Starts fine. Drives fine. Everything seem fine. Perhaps it's just old and probably gonna die in the near future??
