    Golf Mk7 r Motorway speed vibration

    Hi All,

    Been lurking on this and other Forums recently trying to get a definitive answer on a vibration problem that I have had since hitting a curb in ice in Feb. both Nearside wheels mounted a sloping kerb at around 25-30mph (and possibly inner rims of drivers side).

    My journey so far has inlcuded the following;

    both passenger wheels have been professionally straightened as they had been buckled by the impact.
    4 wheel alignment (all camber and toe within tolerance) and full road force balancing completed on all 4 corners
    Inspection by VW "specialist" - inconclusive, but suggestion of driveshaft or inner CV damage (unsure whether front or back)
    Inspection by "trusted local" garage - similar diagnosis, but also suggestion that Diff may be damaged.

    Symptoms are that at speeds below around 60mph there is no or very little vibration, but over 60 there is a very noticeable vibration that can be felt through the passenger footwell (and also through the car). No noticeable vibration through the steering wheel.

    If I tweak the steering wheel to the right above 60mph or through sweeping right hand bend the vibration is worse - feels like more of a buzzing - similar to you would experience driving over the rumble strips on Motorway hard shoulder or armco line. seems to be more than one vibration per revolution so I am thinking driveshaft may be correct but just don't understand why it is worse when steering right.

    Leaning towards swapping front driveshaft and C.V assembly but feel that this is going to start getting very expensive unless I can get a proper diagnosis.

    Thanks in advance.

    The VW workshop system forbids the straightening of wheels. Fit new wheels and try again.

    Vile Invention

    Dark was that day when Diesel conceived his grim engine that begot you, vile invention, more vicious, more criminal than the camera even, metallic monstrosity, bale and bane of our culture, chief woe of our Commonweal. How dare the Law prohibit hashish and heroin yet license your use, who inflate all weak inferior egos? Their addicts only do harm to their own lives: you poison the lungs of the innocent, your din dithers the peaceful, and on choked roads hundreds must daily die by chance-medley. Nimble technicians, surely you should hang your heads in shame. Your wit works mighty wonders, has landed men on the Moon, replaced brains by computers, and can smithy a "smart" bomb. It is a crying scandal that you cannot take the time or be bothered to build us, what sanity knows we need, an odorless and noiseless staid little electric brougham.
