Thread: shims for diff angle

    shims for diff angle

    ive lowered my car two inches in the rear with lowering blocks

    my new diff was silent now im getting vibration from 30-80kph and when on an doff power its clunking
    i assume the diff angle is out and will need shims

    anyone have a rough guide to what degree i will need ?
    from googling it seems to be 304 degrees

    is this tilting the flange of the diff up or down ?

    If it is the diff angle contributing, the diff nose should point down by around 2 degrees.

    I'd be checking everything else first though. Everything tight? Tail shaft perfect? etc.

    everythings tight and seated the diff is pointing up

    there is no one near by who has any idea how to measure the angles well within 400km
    3 or 4 degrees ill just have to buy some and try

    A lowering might have exacerbated an underlying issue, but sounds like your confident everything's sweet.

    I'd do some youtubing. Stringlines and a protractor + or - a spirit level could get you a long way.

    Reckon you will be able to tune it out with some wedges though. Somewhere near level should do the trick. -2 degrees is more for big power stuff or if your trying to launch it off the line.
