Zil - are the Metro uprights front or rear steer then? I'm guessing rear steer as it's transverse FWD. Otherwise they'd seem ideal for a 7 type vehicle.
I have a question about converting hubs.
I have a set of servicable fiesta hubs sitting around, which are clearly FWD. Is there any way to replace the axle drive shaft with some replacement
to keep the holding torque on the hub.
Without something of that sort (a high tensile M24 bolt, perhaps, or a cut stub?) I'm sure the forces on the hub would rip the bearings out of
the upright.
Any experience with these, or do I consign the hubs to the scrap heap?
Strip the end off the driveshaft and get the CV tripode yoke turned down in a lathe (not strictly necessary, but will save a good chunk of weight)
then reassemble into the upright.
Might be tricky holding the remains of the driveshaft still while you tighten the hub nut though.

I figured that would be the easiest way. Better dig out those old shafts - if I haven't chucked 'em.
Thanks for the quick reply.
you going to use them on a 7? seems a bit pointless really as you could easily get hold of sierra ones for very little and definitely less than altering the fiesta parts. Sell what you’ve got on e-bay and use that to help pay for something more appropriate.

Oooh wait till I get to work next week and rib my boss about his beloved MGF being Metro based - that'll wind him up a treat

I'm not sure of splines etc but the last shape transits in rwd form had an insert in front hub
Much like the mentioned cv joint done in a lathe

I converted a sierra 4x4 front end to 2wd by removing the CV.
TT
I did similiar with mine, but using all custom parts....more pics on the site.

If they are going onto fabricated wishbones, or even indeed using standard metro bones, you would be free to choose where your pickup points are on
the chassis. At the very least you can still choose caster angle and swap them over side to side. KPI you would be stuck with, but thats still the
case if they stay as they are.
I tend to think (and would be pleased to be put right if I am wrong) that the scrub radius for these bits is way better than using a Sierra hub with a
mushroom.

@ Alan B
Very, very impressive work! All your own design?
I'm intrigued by one image in particular:

It looks here like the insert is not splined to fit into the splined hub. Is that correct? If so, has it caused any problems where the spline tops
mounts on the insert?
I like the solution to the problem, though. Did you machine them yourself?
~b
Baz, thanks.
The insert is not splined, it's a couple of thou' less in diameter than the spline ID. I believe it's only serving to clamp it all
together in this application so fitting the splines is not required IMO.
So far I have seen no problems.
Yes, it's all designed and machined by me.
Alan
Alan - I'm assuming you have a fair amount of machining experience - especially looking at those uprights! CNC'd?
My wife looks incredulous that I could get so excited about a plate of metal. 
What steel did you for the bolt?
baz
Baz, again thanks.
No, the uprights are plasma cut, bent and welded.
The bolt part actually is a bolt, 3/4 UNF high tensile IIRC which I ended up drilling right through with a 10mm hole (IIRC)
The bigger part was turned from solid.
If I'd had spare stub shafts available I would have modified them, but I didn't hence machining from solid. At least with being hollow
it's a pretty lightweight solution.

The MGTF rear upright is a pretty neat item.
