    "Bad Vibrations": Steering-Wheel, Tires

    Since three months I have my X5 with Sport package with "Michelin
    Diamaris" tires 255/50/19 front and 285/45/19 rear.
    From the first day on the Steering-Wheel vibrates at a speed of 50miles/h and 75miles/h. Vibrations are getting worse right in the moment when you start braking.
    My dealer already changed the brakes and Michelin changed the tires
    already two times, but the vibrations are still the same.
    Does anyone out there have similar experiences and a solution for it?

    Have the wheels checked

    One or more could be out-of-round. If you take it to someone who knows what they are soing, they should be able to test the wheel trueness, as well as the tire trueness, balance, and alignment. More investigation is needed.

    Re: Have the wheels checked

    Thanks for your reply!
    Here's what Michelin already did/said:
    -they tested the wheel trueness and tire trueness twice (each time when they changed the tires)
    -balancing took them 4 hours, when they changed the tires
    the second time
    I think that the vibrations are caused by the Michelin tires...

    Bad Vibrations - resolved

    I had a similar problem - although when I changed the front brake pads the problem seemed to go away -- The vibration came back in about 15K miles -- The vibration was being caused by the right front brake caliper piston not returning to its proper position in the caliper cylinder. The problem would however only occur after the new pads were used for 15K miles -- In other words the piston only stopped returning to its normal ..disengaged position after 15K miles.. I replaced the caliper with a rebuilt unit from Summit racing for about $75. and the vibration never returned.
