    Loud THUNK

    When I brake and come to a stop and start rolling back in neutral (5spd here) I hear a crunch/ thunk, any ideas what it might be, I looked under the car and didn't find anything out of place, id have to put it on the lift and really see whats up.

    Re: Loud THUNK

    Checked both, its not it, it feels directly in the center of the car, like the drive shaft, had the car on the lift, nothing is loose, no idea whats making it, kinda feels like the brakes are sticking, but not really. Any ideas?

    put it in 1st gear and let it roll back w/ clutch in, see if it still happens.
    Do the same w/ reverse. that will narrow it down to tranny or drivetrain.
