A blow-molded wheel including an axle retainer assembly. The retainer assembly includes a housing having transverse sleeves that support an axle and a spring biased retainer pin that mounts to an annular groove at the axle. The housing is supported in a cavity formed into a wheel spoke and a bore of a wheel hub and is retained upon the shrinkage of the plastic around the housing. An aperture of the pin sleeve facilitates retraction of the pin and release of the wheel from the axle.
