    Default Loud Noise, Bad Vibration...out of ideas.

    Hey guys, this is my first post, but I have tried searching around. My wife's 2003 Focus ZE3, has recently developed an awfully loud noise when her car is cold, this will continue until you drive around for 45 minutes, which only makes it a bit quieter, but not fully gone. It's accompanied by a shaking, that vibrates the whole dash. Driving will lessen the noise, or switching into another gear will lessen it for a second.

    There isn't a CEL, or any other indicators. There doesn't seem to be a loss of performance either.

    Work Done: Oil Change, and Filter. New Air Filter, New Tires (Few months back), New PCV Valve, Fluids topped off.

    She sits right at 70k miles. Any thoughts? I apologize if this is something you guys answer a lot.

    :beer:

    Welcome to FJ.

    Check your motor mounts, the vibration with no loss of power sounds like all are bad. Pop the plastic top off the passenger side mount and see if it looks collapsed, sunk down, it should be a bit dome shaped if it's good. Also, remove the airbox and push your finger nail into the trans mount if it's hard, it's dried out and no good. The lower mount might be okay or it might be torn. The top two will make the most vibration, but if you need to change the top ones, you might as well change all.

    passenger side engine mount usually goes and vibrates the whole car at idle- also check the roll mount underneath the car and make sure there is no debris or anything stuck on it

    I had the same issue with my 2002 ZX5 a couple months ago, bought a new passenger side motor mount from the Ford dealership, replaced it and its like a Cadillac now!

    If it were the motor mounts, would it still go away after awhile? After about 30 minutes, it quites down a lot and the vibration goes away as well.

    With the holidays, I haven't had much time to look into it, when I popped the hood this weekend, the noise seemed to be coming from the back of the engine.

    It doesn't have to be the motor mounts, that's just the first and best place to start eliminating possibilities. Once you've checked them in the way I suggested above, then you will know more. Also, when rubber warms up it gets a bit softer, so your mounts could act like that.


    Also, can you describe the sound of the noise a bit better?

    It's hard to describe, but it's almost a kind of clicking sound.

    get it to a shop soon...anything in the rotating assembly usually gets more expensive the longer you wait

    A clicking noise could be a belt bearing as suggested, but if it's coming from the back of the motor, then it's probably your alternator bearings. If you try the belt removal diagnostic, remember the path of the belt (get a diagram), and if that doesn't stop the sound, then listen closer to see if it's a bearing associated with the timing belt.

    I'm new as well, and my 2003 Ford Focus is having a similar problem. When I start the car in the morning, it makes a loud noise and there is a lot of vibration. As soon as I shift into reverse both the noise and the vibration diminish and from that point on, it seems to settle down and run more smoothly. It doesn't take 45 minutes for mine to even out -- it's really better within minutes of driving, but I'm increasingly concerned about the noise when I start it. The last work I had done in a shop was a tune-up and replacement of the timing belt. It was actually after that that I started to notice the noise and sometimes the engine would misfire. My husband replaced the spark plug wires, so the misfiring has gotten better, but the noise and vibration on start-up is still the same. Like the other poster, I'm curious about why the noise and vibration are only bad at start-up and not while driving.

    it sounds like your wheel/hub bearings. mine went bad at around 74k miles and my car would get sooo loud and shake like a mother !!!
