B. If the lock-in wedge has been previously installed, it must be inspected for proper installation. Inspect to make sure the flange of the lock-in wedge is flush with the edge of the pawl. Place a small screwdriver between the lock-in wedge and the sector gear. Apply a firm, up and down prying force to the wedge. The wedge should feel very stiff, with no movement between the sector gear, wedge and pawl.
