    Need help: Remove Power Pump Steering Shaft Seal?

    I messed up the title, its the power steering pump.

    I have the pump dissassembled and I have replaced every seal but the shaft seal. I do not know how to take it out. I though the shaft comes out and then the seal would be pryable with a flat head but i cant see how to get the shaft off. I dont see any snap rings.

    It is a pressed in seal. So a seal puller carefully used should do it.

    Looking at the exploded drawing shows a snap ring behind the seal holding the bearing in the housing. Then another one in front of the rotor and vane assembly. So you would have to take the complete pump apart to get to that one. Also the shaft is probably a press fit into the bearing and the bearing is a press fit into the housing.
    With the puller you just slide the hook through the rubber part of the seal trying to stay away from the shaft and rock the seal out (pry gently). Just keep in mind if you gouge the shaft then you wasted your time trying to replace the seal.

    The thing is, I don't know how to get that giant thing in there with the shaft in the way.
    I have found this on the internet: https://www.homedepot.com/p/Lisle-Sh...B&gclsrc=aw.ds

    It's called a "Shaft Type Seal Puller". It seems to be the thing I need for the job. Thanks anyway.

    Cool

    Another way is to use a non-tapered wood screw and a small slide hammer.
    You may choose to MAKE a hook to jam into the seal to pry it out.
    Use the end of the shaft as a fulcrum.
    Just carefully drill a small hole into the metal part of the seal and use a wood screw.Not a self-tapping one.
    You want to avoid metal chips in there.

    I already did that and failed to find a sliding hammer :/ the local rental one was huuuggeee. I did put a flat head against the bottom head of the screw and tap it with a hammer for 10 minutes but seal didnt budge.

    OK,I believe you!
    Drill small hole in the metal part of the seal and use a little bigger screw.
    You may use a HEAT GUN to soften the seal and the aluminum housing.
    The aluminum will expand and allow seal removal. It will also soften the FIPG if it was used to seal the seal.
    Use a long-ass wood screw. Maybe 2 of 'em.

    That should work. It all should work some methods are easier that others. Just don't have large or wide lip to work with on the pump.

    just tap tap tap the shaft out with a brass hammer or use a press. It is just press fit into the bearing behind that seal. I recommend replacing the bearing and seal if it was leaking, as the leaking PS fluid probably contaminated the grease inside the sealed bearing and it won't be long until your power steering pump starts to go SCREEEEEEEEEEEEE.

    Once the shaft is out, it is pretty easy to remove the bearing and seal with a punch.
