    bad struts??

    Will bad struts cause vibration at 60mph??
    I just replaced both front trust arm to take care the vibration. 90% is gone.. However, it still have light vibration st 60mgh even without the brake. After I passed 60mph, no more shaking. I did noticed the driver side strut is leaking badly when I did the trust arms.

    Any comments or suggestions is welcome.

    TIA

    Uh . . Yes!

    Although the strut that is "leaking badly" should be good for another 10K miles. Sorry, couldn't help myself.

    Worn out struts can definitely cause vibration, whether or not they are so bad that they are leaking. And 125k miles is the strut life predicted by some experts on this board, like Jim Cash. However, I just had to change mine at 83k miles for the same symptoms you mentioned, except they were not leaking yet.

    Thanks for sharing your experience. I was thinking bad strut would only give me bouncy ride. Didn't expect it will vibrate. Now I am shopping for replacement struts. What is the best source?

    Struts

    These BMWs don't bounce freely when the struts first wear out like American cars. They just stop damping some oscillations like wheel imbalance that shows up at certain speeds, or driving on washboard surfaces.

    For sources for Sachs Boge (OEM supplier), you can either get the exact part number from the strut on the car itself or from the RealOEM.com website, and search sources like Pelican, RM European, etc. Alternatively, you can just go to RM European, AutohausAZ, or others and just enter your car info, and they will suggest a Sachs strut for you. Strangely, the Sachs strut suggested by this method is usually not the exact replacement Sachs strut, and may be cheaper. Some people like Bilstein replacement struts; not me. If you also replace the strut mounts, do not get ones by Üro.
