Upon thorough inspection this morning, I think this is what happened;
The wheel that came off had been over-tightened by the garage.
When I took this off (which nearly killed me) and replaced it with another wheel, I cross-threaded it or didn't tighten the bolts up enough.
When this wheel fell off, it damaged the inner lip of the wheel itself meaning it could never be fitted flush again to the hub. So no matter how many times I tightened it, it was always wobbly.
I've put another wheel on the car, checked all the bolts and am off for a test drive in a minute.
If I don't return, I'm in a hedge, but thank you for all your inputs. Much appreciated.
