As Karl said - wheel bearings aren't cheap though, so you might want to inspect when you have the hubs off and if any need replacing, you could put it back together and then replace once you've bought the bearings. It's not a massive job to change out the wheel bearings later.
I would add thrust washers and lock nuts (bearings nuts as Karl called them) as the thrust washers wear quite quickly being soft. The lock nuts are prime candidates for damage from the previous owner using a chisel to loosen and tighten them if he didn't have a big enough socket, so don't be surprised if these look nasty. These are the 54mm nuts that you need your socket/box-spanner for. If they are mangled, you might not get the socket on them and be forced to use a chisel or screw-driver to remove them - in that case, you'd definitely want to put new ones in in order to torque them up properly with a torque wrench. Lock nuts are only a few quid, so worth having some as spares anyway.
If you end up going back into the hub to replace wheelbearings at a later date, you'll be removing the lock nuts, tab washer and thrush washer anyway, so could replace these items then if necessary.
It's probably worth getting some steering arm studs and cone washers as these are often broken or have fallen out - and even if you don't need them now, they're important spares to have and pretty cheap too. Remember to clean the threads of the knuckle housing properly and lock-tite the new ones in
Remember to use moly grease for the CVs!
I'm assuming you'll follow the various guides on here - you will be fine with them!

But again something worth keeping in the parts bin.
Chris, you ok mate?
