Hello everyone. I just got done fixing a mystery misfire issue with my 2011 328i. Not even a week later my car has decided to throw two new problems my way. Not sure if they are related or not but I could really use your help!

The clunk is coming from the front driver wheel. (70% sure) it happens when I go over a sharp but not deep bump. The driving characteristics of the car seem unaffected. I checked if the sway end links were loose and they seem pretty solid.

The squeak/squeal I'm getting is during any form of acceleration when the engine is between 2 and 3 thousand rpm. Its very loud and makes everyone stop and stare haha.

It ONLY happens when i give the car a medium to high amount of throttle. If I put the clutch in or take my foot off the gas the sound goes away. If I rev while stationary/not in gear there is no noise either.

Oddly enough it sometimes happens in reverse as well but it doesn't really correlate to the speed/rpm but seems to correlate to the load.


I made a video of my squeak/squeal. It was a challenge driving stick and filming at the same time. I'll eventually get one of the clunk if I can.

Thanks for your help!

I suspect its the driveshaft squeaking and the tie rod ends clunking.

How does one grease or lube up the driveshaft? Easy access?

Never heard that before...
Have you been underneath the car at all since you discovered the sound????

You can imagine one person trying to figure out where the noise is coming from. A garage told me its from the driveshaft area but I really dont know what to look for. No clunking or anything from the driveline just this annoying squeal.

I'm suspecting its the main u joint but since its not greasable maybe I can syringe some grease in there?

Think decent grease can even squeeze through a syringe? Am I wasting my time?

Thank you for your help!

Hey, just bumping, did you ever get this figured out? Having the EXACT same noise on my 07 328xi.

I don’t know the OP’s outcome but because he said when he pushes the clutch the squeak goes away I would first suspect the throw out bearing is the cause. Anytime the car is in motion the driveshaft is turning, and pushing the clutch doesn’t change that.

My 06 325I makes similar sounds at low speeds. I cannot hear the issue with all the wind noise at higher speeds. My mechanic raised the car and checked the wheels for play. I could have swore it was a driveshaft issue but then he showed me all the wobble from the rear right wheel. Most likely a bearing in my case as all the bushings appeared fine.
