Copper grease between alloy and hub?

I'm fairly certain that, somewhere, CW has just seen this thread and had a heart attack :D

 

 

He's seen it, he understands the mechanism of wheel to hub interfaces and is agreed with by experts, so is going back to making some FCD's while you all smear Coppaslip on hub to rim interfaces. He also asks to be shown a new car with grease on the hub / rim interface and waits patiently.... :)

Seems like a toss up between wanting to stop corrosion/ease of removal and risking having a "soft joint" between mating surfaces.

 

Surely if you are creating a soft joint, then just checking your wheel nut torque every now and then is all thats needed, especially on a road car.

 

Sharing a workshop with some bmw fanatics, I get to see a lot of stock bmw's that need the wheels kicked properly to get them to come off the hub once wheel nuts are off.

Hmm, interesting stuff. As my original point, the use of lubricant on the threads only becomes a problem if the bolts are over tightened and not torqued correctly. Therefore the spring in the bolt is lost.

 

Good point about the soft joint but would a correctly torqued group of bolts really be affected by the soft joint in real life conditions. We are only talking a minimal amount of grease. Would love to see figures on how it affects the clamp force.

Ok, now stumbled across a debate about torque wrenches being crap for judging bolt tightness. This is giving me a headache. I have never had a wheel come off or valve top come flying off so I am going to stick with my principles, not matter how flawed they may be. Doing a City & Guilds, NVQ level III is not everything it's cracked up to be apparently..!!
