It was a pleasure working with the seller, he happened to send me the wrong batch, processed quickly and sent me the correct package . The product is of excellent quality and easy to install. It is recommended to use a wire wheel or sandpaper to clean the axle shaft where it will move in the seal. Put some lube on the rubber end where it enters the axle tube and make sure the lubricator is easily accessible. I used a 2x4 section to put them on the axle. Then apply some assembly grease to the axle to avoid damaging the lip seal when inserting the axle. Otherwise excellent quality, yes you will need to remove the plastic protector that comes from the factory on the axle shaft as that is where the seal moves. I'm glad I no longer have to worry about fine sludge getting into the axle tube and ruining the axle's internal seals.
