they came off nicely not tight and they didn't fall off either. the new one went on with just a slight thump with a hammer and a lump of wood.
Thumping a bearing is not a good idea.
I can't remember whether the rear Early Mondeo bearings went onto a stub axle or into a hub carrier (most likely the former), but they should ideally be pressed on/in.
If a press is not available, or the hub/stub axle is not dismanled from the car, then one of the folowing would cause least damage:
If the bearing goes onto a stub axle then only the inner part (track) of the bearing should be tapped in with copper or brass drift.
If the bearing goes into a carrier then only the outer part (track) should be thumped in with a soft drift.
This ensures that the ball bearings don't get damaged. Damaged balls will create a rumbling/droning at best and will wear out the bearing in a short period at worst.

Yes, that's what I was driving at - it's very easy to damage bearings like this.

the bearings come complete in the hub. that's why they cost upwards of 60 quid each. stupid design, my old escort had removable bearings that went into the hub/drum assy. much better and cheaper.
by thump i mean slightly more pressure than a tap. not so easy as to show the stub axle isn't worn.

Many years ago I remember watching someone in the local BMC garage tightening a hub nut by jumping on a 2-foot tommy bar ...

Didn't do it tight enough then?
He'd have his mate joining him if it'd been a VW Beetle or a Skoda Estelle rear hub nut. ;>)
