Wheels stuck to axle (and wheel alignments)

I have two questions:-

1. I had a puncture last night. I jacked the car and loosened the nuts but the wheel would not come lose - it was "stuck" onto the axle.

I called out the emergency breakdown service - they freed it by hitting it from underneath the car while I pulled from outside. It took the two of us as he could not do this on his own.

Is this common? If so, is there anything I can do to stop it from happenind again?

2. I took the car to have the wheels aligned. They only had data for a 2013 Golf - are the measurements the same for all Mk7's?

Wheels sticking to the hub because of "dissimilar metal corrosion" is very common & old news..my first car way back in 1994 had this....

The car manufactures do not see this as a problem & refuse to solve it....

The solution is to remove the wheels & apply a thin film of copper grease to the mating surfaces...infact you will notice that the wheel contact area is smaller than the hub so apply to the wheel only & around the inside of the centre bore of the wheel & the sticking out olive section on the hub.

Then also apply a thin film to the bolts & the radius ball part which tightens up against the wheel...

As for wheel spec, 2013 onwards it what it should say....where did you take it...

Anti sieze.
Thin film.
Also helps reduce rust.
Wipe down apply again at wheel rotation or change.
