Thanks Nick W for your post. Your kit looks just the job. I have the bearing kit, just need to source/make the special tools you have. Will save the old inner bearing bits to pull the hub flange back in, if I get that far.

You can pull the hub back through the bearing using it's own threads and some suitable spacers; the old inner race can be used if it's a now loose fit, and I have an old one bored out 1mm to do the same thing.

Trying to picture how this would work?

Thinking of buying the bearing from carparts4less. They are showing a number of suitable bearings. Considering the Lucas @ £31.14

Please keep us in touch as the job progresses, Berserkerboy. It's a job I have never done, and which frightens me. I used to scrap cars with failed clutches or blown head gaskets, now I can repair them. I still cannot change tyres. Nick says RWBs can be changed in 2 hours in the street. I should allow more time than that, like a week, but I hope you get there in the end. Good luck!

Struggling at the first hurdle!

Thought I'd try to undo some bolts before I take everything apart, specifically the 6 bolts holding the half shaft to the drive flange. 8mm hex but even tho I have cleaned up and sprayed with release fluid they just wont budge with the allen key I have. I've ordered up a 1/2" drive 8mm hex bit in the hope that I can get a bit more on it.
Is it okay to put the engine in park to keep the wheel stationary while I try to loosen them off? Didn't want to have to make anything to hold the wheel as suggested in the maintenance guide on the subject.

Screw two adjacent wheelbolts into the hub and hold it steady with a prybar between them.

Got it :) Will have to wait for the 1/2 inch drive to arrive from the bay.

I don't think so. I've never had any trouble undoing them with an ordinary 3/8 ratchet.

Pop the wheel back on and jack that corner high. Lower onto a ramp, undo any bolts in reach, re jack, rotate wheel a 1/4 turn, lower and repeat. Let the weight of the car do the work :y

Hex nuts undone. Neilson set from the bay £7 ish was a good investment. Anyone attempting this, you will not get them undone with an allen key and risk rounding the bolt off.
Wondering if I can get the 300NM nut off of the bearing by using Nick W's or Harris K Telemachers techniques with just the handbrake on or whether I need to make the anti rotation device as shown in the maintenance guide?

For the record my suggestion was for cracking the hex bolts ;)

Pry bar across the wheelbolts works fine for this. Chances are, if the bearing is knackered you'll find it isn't particularly tight. Doing it up to 300Nm can be interesting due to lack of access

300Nm bolt undone. You were right Nick, didn't seem particularly tight. Really wishing I'd been quick enough to buy the tools I was offered above as I'm struggling to get the drive flange off. Knocked up a strap with a nut welded on but it's just bending the 3mm steel. Need to weld on a bit of strengthening. Then looking forward to pushing out the hub....Not!

I use a Mini flywheel puller with one of the slots filled slightly to get two of the drive flange bolts in it. This is nowhere near centered, but the drive flange isn't a tight fit on the splines, and so it works effectively. You only need to start it moving. Flat 3mm steel is a little optimistic, but doubling it up should work.

Strap MK2 did the trick. Gave up on the 3mm and used a piece of angle iron (about 5mm) and an M16 nut and bolt. Will dismantle brakes tomorrow and figure out how to push hub out of bearing.
