2008 535i clunking noise
Hey everyone,
I recently purchased a used 2008 535i with 105k miles. It's making a clunking/rattle noise over bumpy roads and driving over the smallest of uneven surfaces may cause it to happen. It can get loud and annoying, as im sure some of you may already know. I had my mechanic take look at it asap and we noticed the front end control arms were shot and needed be replaced. So I ended up getting new control arms and ball joint assemblies, stabilizer bar links, and steering tie rod. It all came together in a kit by Meyle with mostly HD parts. After installation and alignment, the vehicle seems to feel and handle well. However, the noise over bumps still continues and did not get any better. We suspect it is most likely the struts and strut mounts as there is not much else to replace up front, although, I wouldnt know myself as I am not a mechanic. I thought I should get some advice/opinions from other people, so here I am. Thanks in advance to anyone who can be helpful!

Bummer that he didn't figure out the clunking before the alignment because presumable you would need another alignment after removing the front struts. You replaced all the things I would have guessed it to be so I agree that looking at struts or upper shock mounts is a good place to start. You're sure it's not coming from the rear-end at all?

It definitely sounds like it's up front. Especially the front driver side. I'm also getting a creaking/squeaking sound now after the installation of the new parts. It occurs when I accelerate from a stop, or when braking coming to a stop, or making a turn. It appears i'm cursed with annoying bmw noises lol
If not that could be the cause for the new sounds you’re experiencing.

If you have active sway, see somebody who can run it through the self-test. They'll be able to pinpoint noises without even driving it if it's anything to do with the sways.

Couple ideas:
- Loosen all the new bushings, rest the car on the tires so it is loaded up as stated above, then retorque.
- Grease the sway bar bushings
- Check/replace motor mounts

It was indeed pre loaded and torqued down properly. We were able to jack the car back up and pinpoint the new creaking/squeak noise. One of driver side control arm bolts needed to be tightened a tad bit more. So far so good. However, still clunking over bumps. Next up is the struts and mounts, fingers crossed.
