I've got some instructions for putting a strut back in to the wheel carrier for my car and it suggests using WD40. As I understand it a lot of people use WD40 as a lubricant, but that isn't what it is meant for. I've got spray grease available too, wondering if that would be a better choice.
Opinions please.

Always grease, preferably lithium based.

Tend to use copaslip for that type of application - hopefully helps removal years down the line

Ooooh yeah I have a tub of copper grease too. Grand, will see if that makes getting this damn strut in to the right place easier. Thanks chaps  |

What car is it? You shouldn’t need any sort of grease or lubricant to fit or remove a strut attached to a hub with a pinch bolt assembly. You just need the right tool to open the hub up to allow the strut to fall in. You can make one from a large bolt ground down into a rectangle on the end. The narrow part needs to just fit in the gap and the the wider part opens the hub up when you rotate the bolt 90 degrees. Hopefully that makes sense

Hopefully that makes sense You shouldn't need to beat off stuck alloy wheels with a length of 2x4, drill out snapped exhaust bolts or rounded off screw heads, helicoil stripped spark plug threads, or cut both sides of a bolt that's rusted to the inner sleeve of a bush, but none of those are unusual. |

All of which could be alleviated with the application of a little non stick compound at the original (or subsequent fitment) But what the heck - life is for living |

A tub of coppergrease should be on every mechanic's shelf. Drill a hole in the lid, and keep an acid brush in it for instant use. |

Exactly what I do - except I cut the brush down so it fits in the tin with the lid on |

You shouldn't be using lubricant on any critical joint that relies on friction to hold it together, might make it easier to get it appart but it might move when it's not intended to.
On critical bolts best to use a threadlock which will also provide some protection against corrosion rather than a lubricant.

On critical bolts best to use a threadlock which will also provide some protection against corrosion rather than a lubricant. Sometimes people don’t want to listen to that. Brake calliper retaining bolts that are single use that have been re used and fitted with a lashing of copper grease is something I usually see on cars that have been worked on by the local copper grease fanatics. My tool box has a draw full of the correct sprays, greases and locking fluids that are approved for use in different areas. I can get a photo of the tool I described above so you can make one. It does the job just right for removing and refitting struts with pinch bolts |
