Wheel stuck on hub: help.

requires a little bravery, is to loosen the wheel nuts by a few turns, then go for a slow drive down the street which will hopefully release the wheel.
The car is worth about 10K. I'd prefer to avoid this if possible.If you're going to lower the jack so that the wheel comes down onto the ground and has full load on it, I wouldn't loosen the wheel nuts "a few turns": it would be no more than about half a turn, especially if you're going to try driving the car a short distance. All you need to do is make sure the wheel nuts are no longer clamping the wheel onto the hub. Any looser than that and you risk doing some damage to wheel studs or the wheel itself when the wheel comes unstuck from the hub.

Could some kind soul explain what the problem is with applying copper grease. Just greased my hubs after fitting winter wheels and would like to know.
No problem at all.CraigyMc said:

Just crack the wheel nuts half a turn and let the weight of the car do the work for you if it's stuck.Blue62 said:

Practically, probably none. But since the wheel is held to the hub by friction between the mating faces, putting grease on them reduces that friction, so probably isn't a great idea. However there generally seems to be enough margin for error that it doesn't cause a problem.CrutyRammers said:

I figured that is the issue and thanks for the other responses. I will keep using the grease on my alloys, but sparingly and to the OP I would recommend he purchase a rubber mallet, works for me.CrutyRammers said:

Is the transmission of acceleration and braking torque really dependent on friction between the wheel and hub? I'd have thought the wheel studs took care of that, with the nuts seating into conical areas of the wheel; unless the design details are different these days.
You're right.Think about the difference in friction between a shiny new wheel on a shiny new disk, versus a manky steel that's been hung under a boot floor as a spare onto a manky near-end-of-life disk.
The most likely place for corrosion to cause a significant issue is between the spigot and the spigot hole.
As mentioned above the clamping force window for normal vehicles is sufficient that application of a very small amount is not that detrimental. Larger vehicles though it's an absolute
I use the loosen the wheel bolts method and do them up finger tight. Slow drive with a little wiggle and you can hear the wheel come "loose" except it isn't actually loose. Tighten the nuts back up, drive back the few yards to starting point and bob is your uncle.

Put the wheel nuts/bolts on loosely and drive up and down the drive/road, this should do it.
Don't do this! Highly dangerous not to mention running the risk of shearing bolts!I am not telling him to get on the motorway, just to turn the wheels a few revolutions and I suggested the road because I don't know if he has a drive.
