    Hello All,

    I have tried to read all posts regarding squeaking possibly from the rear non-driver-side suspension, and I seem to be leaving with more questions than answers. From what I read, when people ask about squeaking from the suspension, people seem to want to know whether the squeaking is happening at high speed or low speed, braking or accelerating, and is it when going over bumps and such.

    I will try my best to answer these question.
    1. High speed or low speed?
    A. It feels like both. As long as my car is moving, it is squeaking

    2. Braking or accelerating?
    A. The sound seems to happen when the car is going over the road. No discernible difference when accelerating or braking.

    3. When it is going over bumps or not?
    A. Basically, when the car is driving along the road, it squeaks, and it may be more pronounced when I roll over a bump or groove.

    If there is any other questions that I should ask in this diagnosis, please let me know

    Thank you and regards,

    Shih Fa Kao
