Jan, Jack under main frame rail (jack that came with car(sizzors is slow but works) lift until the tire is just touching ground. With Brass hammer, begin hitting each ear in succession two or three wacks ( remember lefty - loosey on US drivers side of car, I believe righty loosey on US passenger side)), It man take four or five cirles of the knockoff to get it to release. Then jack car up higher, remove wing and pull assembly off. Clean threads on axle with toothbrush and brake cleaner or another solvent. Clean threads of spinner the same way. Prior to replacing put anti seize compund on axle threads ( thin coat & I put some on the hub and pins as well), put light coat of anti seize on threads of spinner and thread back on after reinstalling wheel. Begin wacking ears in sequence, two wacks each until you belive it is firmly on. Lower car and give each wing two wacks and the safety wire it properly. Remember...the wing on US drivers side will walk anti clockwise if it loosens, so wire to prevent this.)
