How To Fix Leaking Wiper Pivot Seals

  1. '74 Sport
    For the benefit of many of you wondering how to stop a typical leak
    through worn out and deteriorated wiper pivot seals, I am providing
    the following sequence of photos. The first photo is to show you
    how important it is to keep the cowl clear of debris. This pile of
    leaves and twigs were dug out of the cowl by reaching up through
    the fresh air opening on the passenger side of the dash.


    I know most of you wont have the luxury of having your A/C or
    heater box removed to reach up into the cowl to clear the debris, but
    you should know that there are drain holes in the sides of the cowl
    where you can dig out the bulk of the mess. Its not fun and is very
    time consuming, but it may possibly prevent debris clogging up the
    drains and causing water to back up and overflow into the fresh air
    inlet. Or worse, the built up debris provides a place for moisture
    to remain, causing rust to develop around the inlet and on the floor
    of the cowl.

    The following sequence of photos shows how to install the grease
    fittings, seals, gaskets, and caulk strips that are provided in a kit
    sold by Schumacher Creative Services (

    1. Drill 3/16 hole through pivot base.

    2. Hole drilled only through outer wall of pivot base.

    3. Use nut driver or socket to drive grease fitting into pivot base.

    4. Grease fitting installed in pivot base.

    5. Schumachers wiper pivot seal kit.

    6. Liquid soap will ease installation of the new seal.

    7. Its tight, but the new seal will go on with a little persuasion.

    8. Wiper pivots with new seals and gaskets.

    9. New base gasket and rope caulk.

    10. Pivot installed with new seal.

    By the way, dont forget to shoot a little grease into the pivot base
    using the new fitting. You can skip the step of installing the grease
    fitting, but Schumacher says it can prevent water from seeping down
    a loose pivot shaft (and it might do away with a squeaky noise coming
    from a dry one.)

    The kit comes with very concise instructions, but I
    thought I would give you a preview of what you will be getting into.
    You should probably plan on taking the better part of an afternoon to
    replace the seals from start to finish, including replacing the linkage
    arm nylon bushings. But that is a story for another time.

    Don't be afraid, it's not that bad,
