Hi guys...trying to get a wheel bearing and brake job done on my 74. Is the castle nut holding on the stub axle supposed to be super tight or am I missing something? I've never had one put up this much of a fight but never have done a bearing/cv replacement either.
Thanks! - Jeremy |

I have a couple that I have not been able to remove. I guess they just need more heat and a bigger impact gun.

Had one that I couldn't get off either. Had to get help of an impact wrench to get it loose. Even then the darn thing still put up a (very brief) fight before letting go.

I have a couple that I have not been able to remove. I guess they just need more heat and a bigger impact gun. (IMG:style_emoticons/default/agree.gif) Or a breaker bar and a long piece of pipe and lots of heat, a ox /acetylene or even mapp gas torch. |

You don't want to know... really..... Group: Members Posts: 2,514 Joined: 12-September 04 From: Newport Beach, California Member No.: 2,743 |
I keep an old 5 foot long piece of 2 inch galv pipe in my garage for just such occasion.
With a quality breaker bar and a propane torch. I can dam near flip a car over. Go Home Depot and buy a stick of galv pipe. get a short one and long one. You will have cheater bars for life. And the short bar works bitchin for rolling fenders.....!!!! C |

Is the castle nut holding on the rotor supposed to be super tight or am I missing something? I dunno, it's "only" spec'ed to about 250 lb-ft. Plus however much it takes to overcome the rust that holds the nut and stub together. Plus however much it takes to break the cotter pin... (D'OH!) --DD |

make sure you remove the cotter pin first (IMG:style_emoticons/default/chairfall.gif)
recently i was taking apart some 68 911 arms....after breaking both cotter pins off... and tapping em out... the nut fought my impact for a while. soak in wd40.... came back... worked great (IMG:style_emoticons/default/smile.gif) |

Sorry....seriously solvents and physics are your friends (aka PB Blaster and a long breaker bar). I slipped the 4 foot handle off my floor jack over my 2 ft breaker bar to increase the leverage. Oh and chalk the wheels - I pretty much rolled my car out of the garage before mine gave it up. good luck |

Hi guys...thanks for the help. Didn't need to worry about the cotter pin as whomever was in there last didn't put it back in! I stopped to watch some tv and drink a beer (IMG:style_emoticons/default/beerchug.gif) with the neighbor as it soaked in liquid wrench. It broke loose right away after that.
On to the bearing removal!!! (IMG:style_emoticons/default/biggrin.gif) |

I just had the worst ever nut on the 58....I broke a 1/2 breaker bar when using my 3 foot cheater bar. I used heat (MAPP AND Propane) and PB Blaster.
I ended up buying a 3/4 breaker bar with the afore mentioned cheater and a 1 7/16 six point socket.....when it let go it sounded like a .357 going off.... |
