A method of making a rotary wing aircraft bearing (20) that provides constrained relative motion between two rotary wing aircraft members (22)(24) and forms optically distinguishable interior and exterior cured elastomer composition crumbs (44) from void crack (44) propagation and repetitive motion of the rotary wing aircraft members (22)(24). The bearing (20) including an elastomeric mold bonded laminated bearing stack (26) with a plurality of mold bonded alternating layers of nonelastomeric and elastomeric shim member layers (28)(30), and at least one elastomeric layer (30) comprised of an interior elastomer region (36) distal from the exterior surface (32) with an interior cured elastomer composition (38) having at least a first interior optical characteristic ingredient, and an exterior elastomer region (40) proximate to the exterior surface (32) comprised of an exterior cured elastomer composition (42) having at least a second exterior optical characteristic ingredient different to the interior optical characteristic ingredient.
