So I got the 30mm nuts removed from my stub axles. The half shaft on the passenger side came out of the hub easy as cake but, the drivers side will not budge. I've beat the hell out of it with a 3 lb. hammer and brass drift, soaked it with PB blaster, put the nut on backwards and beat on it. Nothing has worked. (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif) I would like to get it out without destroying the bearing.
I've got an air hammer with a pointed chisel I've been thinking about trying, by placing in the hole in the center of the stub axle. I'm afraid it might mushroom out the stub axle. Any suggestions? I need some moral support. |

PB blaster...heat, wait a day...come back.....shoot it with a .357...
The gun part won't help but will make ya feel better... Keep soaking it...you might have to remove the whole arm and press it out. |

Sounds like you're doing it right. It just may take some time (hours, days, weeks (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif) ) until the sucker comes loose. Bondo & I wound up using a puller to push a stub out. Keep at it.

True, true. I'm planning on removing the arm anyways, so maybe pressing it out is the answer. |

Yeah, I did mine on the bench, no press required. I think that some of the "ass" of the maul is absorbed by the rubber swingarm bushings. Get it on a solid surface and you'll have better luck (or at least a better angle for beating the hell out of it.... (IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif) ). Stick with the brass drift for whipping it into submission, I'd almost bet that your chisel and air hammer will have some ill effects on the stub axle....especially if it pops out of the divot (IMG:http://www.914world.com/bbs2/html/emoticons/pinch.gif) . That said, after a good douching with PB, a little vibration set up by some "mild" hammering with the pneumatic might be beneficial in getting the PB where it needs to be, reducing the overall amount of whoopin' required with the BFH.
If it's that stuck, the odds of getting the stub out without damage to the bearing are not good. Might as well bite the bullet (.357) and but a new pair. |

I used a bigger hammer while it was on the car.

You've already damaged the bearing by beating on the assembly, so whack away on it. Stub axles are plentiful .........

Pull like crazy on the axle from the inside. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)
OK, maybe not. Bigger BFH will work. Paul |

Yep, bearing is toast now anyway. I use a slide hammer when I have to. Works great. (IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif) |

Ok got it out. I used a little more hammering, PB Blaster and some heat. Now just to add a bearing to the list.
I'll sure be putting anti-sieze on the stub axles before putting them back in. Thanks all. |

Sorry I didn't get here in time... Anyway, next time go to Schucks* and for about $3 you can rent a hub puller. You attach it's fingers to the hub with lug bolts and then just turn the center bolt to push out the stub axle. For another $3 you can rent their slide-hammer which you can then attach to the hub puller (after removing the center bolt) and three good whacks will have the hub pulled too. With these two tools you can have the stub and hub out in just a minute or two.
