Ah ok, that sounds a bit of a simpler job?

Indeed much simpler. You do not even need to remove a wheel. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing

Hi
That looks like copper grease? You haven't recently taken off your wheels and coated the studs and nuts with copper grease before putting your wheels back on have you? Jim |

It wouldn't/couldn't be forming radial streaks between the studs if it was coming from the studs!

There is a lot of copper grease on the studs, flange and flange bolts so it could have migrated from there if the wheels have only been fitted recently.
If it were me I would check the flange bolts are tight then clean it all up then run it and see if it returns. Would be odd for both flange seals to fail simultaneously unless they have been worked on. It's a static paper gasket so nothing should be wearing, unless the bolts are loose! |

From what I remember doing mine, smear grease on the paper gaskets before fitting them.

Just remember to be gentle with the flange bolts, they have thread sealant on them and go into a blind hole so on occasion can shear, so if you are removing them or loosening to re torque work them back and forward to ease them out.
Ps at this point I expect the spring washer / thread seal / nord lock washer debate to be rekindled  |

I cleaned the threads on mine with a thread chaser, sprayed inside them with brake cleaner then used compressed air to clean them out. I then used new bolts with the thread lock on.
The vehicle was new to me so I used new bolts as I didn't know just how good the existing ones were and didn't want to use old ones which could potentially brake or rust in. |

There are also advantages in replacing the hex bolts with hex socket head capscrews.

Just done that. The hex caps look tidy

Can I ask the advantage of cap head bolts? I have heard of people using them to aid fitting alloys but are there other advantages Also how do you go on with them regarding longevity. Most of the bolts I have encountered have been hex and I wondered how standard hex compared to the Allen socket when trying to remove them after years of being on the truck? I presume you go for BZP to help them last? |

They're cheaper than the equivalent grade with a hex head and much more widely available, and the head is entirely within the "land" of the flange so less likely to damage the wheel. There's no reason why there should be any difference in longevity (why would there be?) and the torque strength of the socket head is at least as great as the hex. I think they look neater too.
You can use BZP, just as you can with hex, but there's no real need. |
