Carrying on from earlier postings, I've re-enacted the procedure and taken some pics.
I do stress this is not an accurate measuring device. However it can get your camber adjustment in the right 'ballpark'. It will do for the short drive to a specialist without wrecking your tyres.
If you feel uncertain or have reservations get a professional to do the adjustment. Constructive criticisms or witticisms are most welcomed.
I accept no liability whatsoever if you decide to use this method and you feck up big time.
Firstly and probably most importantly, as Covkid mentioned, this will not work unless everything you intend using has a proper
true flat edge to it and your vehicle is on a dead flat surface. I got vehicle level by using a thick piece of chipboard, adjusted by laying sand underneath it, then driving front wheels onto board and measuring levels around each edge of front tyres with spirit level. This part took me about 30 minutes to achieve so I've not bothered to re-enact.
In my previous posting I wrote I used a length of 2"x2" baton.
Incorrect! I used an offcut slat from a pine bed base, approx size 6"x1". Don't know why I wrote other size. Brain's still a bit fuzzy as the reality of losing my job (fecking w4nky yankee Lehman Brothers

) finally hits home, I guess!
And relax.
Cut wood to snugly fit just inside wheel rim, either front or back of bearing housing. Spirit level is not touching the ground. Just angle of photo. Try to mount all as vertical (or use another spirit level) as possible and make sure your metre length spirit level vertical plane bubble window is above tyre....

I then adjusted the wishbone rod with an allen key socket until bubble at top of spirit level was just right to centre. This is positive camber. How much positive camber is another question.

It's a ballpark measurement. And as you can see in the background, just to right of spirit level & behind door mirror, a thin black line gets thicker at top. This is a dead vertical mounted drainpipe on garage wall. I know, cos I mounted it

This gives me another visual indicator the setting is positive camber. No technical wizardry here my friends. In this pictre you can see the bubble is just touching the right side line in the window.

Hold wishbone rod in place and tighten nut to correct torque settings. Whatever that is?...see Wiki?
Check spirit level again, disconnect contraption and do other side to same bubble reading.
Test drive and check again.
I can't stress enough that this is a very rough method of adjusting camber. But I've covered 4K since and no unusual wear to report.
Moderators please E D I T out all the (not all of it

) crap if you decide to Wiki this.
TIP O' THE DAY
And here's an easy tip for removing wheelbearing dust cup.
Use a claw hammer as such....

Go round wheel and do a bit at a time using wheel nut to lean head of hammer against.
