    Grinding/dragging feeling at WOT?

    Guest-only advertisement. Register or Log In now!
    When I floor the car from a standstill or at low speeds ( under 20ish) I get a strange "dragging" sound from the car. It feels like its coming from the rear but I'm not sure....... I just had my 65K tuneup and check and everything was ok from what the dealer saw. I don't have any idea what this could be... Anyone have any idea or similar experience to this? Thanks.

    Unhook the anchor...???

    Maybe an alignment issue...rubbing wheel/tires...wheel bearing?

    Eh, I don't think so, it's only on full throttle and only when I'm at a stop or a slow crawl does this happen.... Would'nt a bad alignment/ wheel bearing cause vibrations going at any high speeds? I'm really starting to worry that it might be the driveline or something... Any more ideas?

    Make sure your rear axle boots arent tore, or else the oil that leaked out will cause expensive damage to the axels if it hasnt already..

    Difficult to imagine quite the noise, but sure sounds like the drivetrain (poss bearings somewhere) if it's related to how much torque you're handing out. WOT in 1st or 2nd is high torque.

    Well I'm bringin the car in on Monday to have the driveline inspected. I've noticed it more and more, now it's not only at WOT in 1st, but also when the car is cold it does that the first few times when I stop at a light, then continue again. It sounds like a diff. or rear axel problem. Still not sure though..
