A method of assembling a camera for a vehicular vision system includes providing a camera housing and forming a post at an interior portion of the camera housing, and positioning a printed circuit board in the camera housing so that the post is received through a hole through the printed circuit board such that a protruding end of the post protrudes from the side of the printed circuit board opposite the imager. Circuitry disposed at one side of the printed circuit board includes an imager. The protruding end of the post is adapted to limit retraction of the post from the hole through the printed circuit board so as to secure the printed circuit board relative to the post and the camera housing. A lens is provided at the camera housing.
