    New engine mount problem

    I installed new polyurethane engine and transmission mounts because my old ones were ruined. I notice a lot more vibrations, the gears are a little more difficult to shift, and I have the impression of hearing noises that I did not hear before. did you have these differences when changing engine mounts?

    Well-known symptoms of poly mounts. A little of the NVH should subside as they break in.

    Mirrors all vibrate now so they are pretty much useless...even the rear view.

    Sheesh, I hope they loosen up for you. That is not cool.
    I didn't realize that they would make that big of a diffence.

    Are your header turnouts touching the frame where they enter the side sills?
