The cleaning of old grease and accumulated impurities from wheel bearings as well as the repacking of such bearings with clean grease is accomplished by mounting bearings to be cleaned in a special manner in conjunction with an appropriate brush and in such manner as to be rotatable by rotating the rotor and further in conjunction with fluid flowing through and about such wheel bearings until the old grease and impurities are removed and the subsequent repacking of the wheel bearings with fresh grease by a pressure packing device.
