£5 per side. You need a punch and hammer other than a decent set of tools to tap the races in.

Don't use a hide hammer or any soft metal
to tap in the bearings or else debri will enter them, make sure you hit the outer
race, if you hit the inner race you will hitting the ball - roller bearings against the outer race which will damage the bearing. Nut tightening is crucial to your safety and bearing life, observe the correct torque wrench settings.
Take your time, wipe all parts clean and you should be ok, there are most definitely different grades of bearings.
Go for a brand name, maybe your local
bearing shop will stock them ? Look in the
yellow pages. When tapping the bearing home ensure it enters the bore squarely,
tap first 12 o'clock, then opposite at 6 o'clock then 3 o'clock and then 9 o'clock.
Repeat equally until the bearing is home, you should hear the frequency change as the bearing bottoms in the housing.
( Frequency = slightly different sound as your tapping )
Good Luck

ps
Make sure you lightly oil the bore to assist
the entry of the bearing. This is just general bearing fitting information. Not sure what are fitted to a Corsa, maybe taper roller bearings, could be single race
ball bearings or indeed single - double thrust race bearings.
I'll have a looksee in the manwell and let you know.

Just checked the manwell, they're
taper roller bearings.
Easiest of the lot, like the other guys
said make sure you replace the seals
and use the correct grease.
Also as Mike says, use a NEW split
pin, torque settings are CRUCIAL to
pre - load the bearing. Use the old
outer race to tap the new outer race
in and don't forget to clean the shaft
so the inner race goes on easily.
The split pin is a SAFETY device to ensure
the castlellated nut does not come loose.
