    It's just a guess on the cost, most of us probably have this hardware already.
    While researching how to install my banjo axle seals I came across some info online
    saying there was a special tool with a long shaft you could buy to drive them home from the wide end of the housing. While I started poking around my shop looking for a way to replicate this I came up with this idea. Rather than bang them in from the inside why don't I draw them in from the outside. This is what I came up with. For all that I know this is an already known method but if not here goes.
    I took a 5/8 bolt, 2 washers and a nut and slipped one washer on the bolt.

    I then wrapped some painters tape around the bolt to mimic the I.D. of the seal. This helps to position the seal and keep it concentric to the bolt shaft.

    Then I lubed up the tape with some bearing grease, slipped on the seal and lubed up the seal O.D. also.

    With my axle housing fixed in a vice I slid this assembly into the axle shaft and fished out the threaded end on the opposite side.

    I then added the second washer and nut and spun it down flush to the axle end. Tightening the nut I could slowly begin feeling the seal draw into the pilot, you can feel when it finds home when the wrench comes to a dead stop.

    Sure beats buying a fancy tool that would hardly get used. Besides I think it is a better method as opposed to beating on the seal.
    Thanks for reading! Stay safe.

    I thought the dark red coating on the outside of a seal was a sealant to be installed dry ,wouldn't greasing it negate its effectiveness ? Just curious ...

    You could very well be right but my guess is that just about all of it got removed by the press fit.

    Smart! I love this kinda stuff.
  7. Something I got into several years back. I found some replacement seals for that job actually didn't fit the Axle shaft properly. Part number was a cross over but not right. The I.D. of the seals were large enough they didn't fit snug on the shaft. Hope you did a test fit. Gear lube on new brake shoes really sucks, almost as bad as taking things apart to replace new seals.
