Differential Crown Wheel Locking Tab is a tab washer used in the axle differential assembly to lock and retain the crown wheel bolts after tightening. Fitted between the bolt head and the crown wheel flange, the tabs are bent up against the bolt flats after torquing to prevent the bolts from loosening under the rotational and shock loads transmitted through the differential. Replacement is recommended whenever the differential is dismantled, as tab washers should not be re-bent once used. Show more
