I feel like the 4020 is the backing plate. I assume the 1001 is a gasket.
Can anyone explain what these are and if I need them?
What about the 1180 & 1177 parts?
Thanks

1177 is the axle seal and 1180 is the axle bearing retainer. The retainer would come with a new axle bearing.JWW wrote:I have removed the axles from the rear end of my 1967 F100. I'm not worried about getting the bearings pressed off and new ones put on. However, when I removed the axles, I don't recall any gaskets. I have looked at ordering the bearings from Rock Auto. They show two different gaskets. I'm not sure what to go with. Here is a diagram:

The (sealed) axle bearings are packed with grease at the time of their manufacture. The gear oil inside the rear end does not lubricate the sealed ball bearings on the axles. The only purpose of the axle seals is to keep the gear oil inside the rear end housing.youngone wrote:Ultraranger, So if I get this right the inner seal in the axel tube stops the oil from getting to the bearing. Are these bearings packed in grease?
Thanks.
