There is red/brown dust where the steering arm attaches to the hub. Does this mean there is movement where there shouldn't be movement? |

I have the same on one of my minis. I suspect movement also and will investigate when I have time. |

Suspect worn holes in the swivel hub or arm. If they are worn oval, tightening the bolts won't help, even with new dowels. I had to change a swivel hub once due to this. |

Are the dowels missing? |

I was expecting something like that. Will be dismantling it soon. At least all the bits are still available. How tight a fit should the dowels be in the hub and in the arm? If the arm needs replacing, should the other side's arm also be replaced too? |

CV is original but not serviceable now; the wheel bearings need replacing and the hub might be worn where the cups sit. Probably due for a refresh. Oddly, the R.H. parts all good to go again. |

Loosen the bolts slightly on the other arm, if you can move it sideways it has a problem too. |

Maybe the dowels rusted out! |

The hub and steering arm are now dismantled. There is a rust issue. Soaking the parts in phosphoric acid to remove the rust and see what is happening. |

Dowell looks like it has some wear |

You need round dowels, round holes and a good fit. |

Was thinking about using bearing retainer on assembling the new dowels. Are there any obvious problems that would create here? Have sourced a good used steering arm and the hub holes are still a tight fit. The rear bolt was under a lot less tension than the other 3 bolts when dismantling them. |

You can try Loctite 609 or similar bearing retainer. I used it successfully to retain a Timken front hub bearing so it should work. If you have trouble dismantling it later use a hot air gun. |

Thanks for that, Dr M. |
