Default Creaking front front suspension HELP!

Hey fellas,

Recently, my 2002 M3 has started making a creaking noise from what sounds like front wheel wells (in that area) whenever the weight shifts; hard braking, sharp turns, and even when slowing down normally when approaching a red light. I can feel a slight "tick" when my left foot is resting on the floorboard of the driverís seat whenever I hear the creak. Has anyone experience this?


I have a few basic suspension mods: Front and rear strut/sway bars and shocks and springs.

Thanks in advance,

TJ

Sway bar end links? Or FCABS?

I initially thought it was the FCABS, but from the research ive done, that wouldn't make a creaking noise (more of a squeak).

I'll check the sway bar links, but im not exactly sure what they are...are they where the sway bar attaches to the strut under the hood?

They attach from the sway bar to the top of the strut in the wheel well. Here are mine:

Hmmm, just got done reading your thread. It appears that you didnt have any noise that you noticed associated with it? The sound that I am hearing seems to almost like a creaking door for a brief second or when hitting a bump. I'm not really car savy so honestly, couldnt make head or tails of the pics. Are the pics shown a place I can access by removing the wheels?

Thanks for your help man,

Tony

I'm experiencing the same issue. Do you have any deterioration in the handling of your car? Does your steering wheel vibrate at high speeds? Does your steering feel overboosted? Do you find yourself correcting your steering to keep the car going straight? Does your front end feel light? If so your FCAB is probably shot. BTW, how many miles do you have on your car? Mine has 72k on it and I just ordered new bushings. If your car is a 2002 and never had the FCAB replaced, then I would look into replacing them. The passenger FCAB is nortorious for failing since the heat from the exhaust manifold thermal cycles it.

I havent had any of the symptoms you described at all. None whatsoever, which is why I thought the FCABs couldnt be the issue. My car has about 50000 miles give or take....

Please let me know if replacing the FCABs fixes your issue.

Could it sound like metal rubbing maybe? Maybe your shocks are out?

I have same the same issue. I have an 02 with 58k on it. I changed the front strut mounts, sway links and fcab's. Suspension feels much better but I still have the squeak and where I really feel it is on the drivers side and also feel play in the drivers side wen I hit bumps making turns. Passenger side was fine before everything was changed and after. Also changed the tie rods or the control arms and squeak was there.

Edit: After changing all that stuff in my suspension my squeaking actually turned out to be my drivers seat. If I bang against the seat I can replicate the squeaking, although it sounds as if the noise is coming from the front suspension while the car is moving.
