I have a Kenmore washer (1970) that I would like to change the center post bearings & seals. I see there are two bearing kits #285134 and #285203 available and I am not sure which one is correct. The upper and lower bearings I have are the same size. When I see the picture of the kit, the #285134 kit looks like the metal bearings are different sizes, and the outer surface has sections (like on an armature), where as the other kit (#285203) outer surface of the bearings is smooth. Just wondering which one is correct. Also, the original part number for the bearing is #54207 and the Whirlpool replacement part is #8546455 and this bearing is smooth on the outside, and it says it's for direct drive washers. All this info. I've gotten from appliance parts websites, so it may not be correct. I know one of the experts here will have an answer. THANKS !!
