WEDGE (Nissan NICK2789599)

A worn wedge can cause instability in the component it secures, leading to misalignment or premature wear of adjacent parts. The wedge is a tapered block that fills a gap or applies force to lock two surfaces together. In the Nissan catalog, this part is referenced as NICK2789599 and is offered as an aftermarket replacement. Its primary mechanical function is to transmit clamping force when driven into a mating slot or cavity. A common failure consequence is that a loose or missing wedge allows vibration and movement, which accelerates damage to surrounding hardware. Keeping the wedge in sound condition helps maintain the intended fit and load distribution within the assembly. Verify the serial number or application, then call (562) 693-7748.
