    My Prius is demonstrating a vibration in the CVT Drive-Train when accelerating at moderate speed.

    Initial acceleration is smooth, 25-40 MPH there is a steady vibration, then at highway speeds it goes away.

    I had a CV axle go dry and replaced it. I also replaced both Control arms. and the other CV axle. After I replace the Struts and inner and outer tie-rods I will have a new front end.

    I am wondering if anyone has had any issues with the CVT mounts or the lower engine torque strut that I would assume could cause vibration if failing.

    I hope that it is not a CVT problem.

    Thanks, John.

    Were seals where axles enter trans replaced when CV joints
    Replaced?
    If not u may be leaking trans fluid.check trans fluid.
    Sometimes trans fails and u will hear and feel vibration
    Front passenger side but in that scenario it will soon
    Throw check engine light for hi volt fault.
    Other way the trans fails is gear wear in diff area of trans
    From lack of fluid maintenance. That will not throw a code
    As strictly mechanical.
    Were u replacing these parts chasing this issue or it happened
    After parts were replaced?
