    Yes , coming with the rest .. re inspecting the driveline IF you have a access plate on the rear mount housing you may be able to reach in and "manipulate" the double U joint abit ... the only real way to check is to pull it out

    Ok. Probably will not worry. Can it be inspected without pulling motor?

    Is this in or out of the water? They tend to rattle when not loaded, at least in my experience. When the jet bearing goes it's usually a continuous growl or whine.

    Does the noise dissappear when you raise the RPMS from idle ?
