Sierra 4x4 front hub assembly ?
Collecting the bits together for my first build, Fireblade engine and Sierra 4x4 so far. Looking at the sierra I get rear discs etc, on the front
vented discs, however looking at the posts I,ve not seen anyone that has used the 4x4 hubs and dumped the driveshafts, so my question is can I use
this ?
Alternatively I have found a mkIII cortina down the breakers with knackered discs etc, can I swap the decent brakes from my sierra across (this is my
prefered route) on the basis that I will have a matched braking system at low cost !
Cheers Mark

apparently the bearings fall out of 4x4 front hubs if used without the shafts. I think using sierra discs on cortina hubs will require spacers at
least, maybe more. Did you read the recent thread about solid vs vented discs? Worth bearing in mind.
Cortina hubs are arguably better geometry than sierra ones.

You could use the 4x4 front hubs, but you'd have to have the outer part of the outer cv joint (the splined bit) there to give something
to bolt the hub nut onto. Would work OK but isn't your best solution, plus you'd then need custom (bigger) strut -> balljoint adapter
things and a special bottom ball joint.
You could get hold of some 2WD front hubs/uprights if you want to stay sierra based (cos you're planning on buying a sierra based kit for
example), but your best solution IMHO would be to get them cortina uprights (rocking horse sh*t) and stick with solid front discs, which will be fine
for a little blade engined car (with an easy later upgrade to nice willwood ally calipers easily available).
As an aside, despite the above recommendation, I have to disagree somewhat with Joel's last statement! Whoever said around 100mm of scrub
radius is desirable? If sierra uprights have anything going for them (it certainly isn't their weight or that of the associated brakes),
it's that they have pretty decent steering geometry compared to cortina ones.

Say Guys, there’s an awful lot of talk about rocking horse poo and Cortina hubs.
Over here in New Zealand (to exaggerate a little) there’s a Mk 4 rotting in every second back yard!
What is worth to you guys, to pay me to source them and post them over? Now I know you’re all tight – that’s why you are building “Low Costs” but make
a realistic offer and I’ll start investigating at this end. Note, the current conversion is 1.76 New Zealand dollars to the Euro.
I suggest the terms could be: I find hubs, ensure that they turn, do a visual check, and post them to you in good faith. The problem is if you want
them with a guarantee, how far do I go to check them and how much is it going to cost you? I don’t want to get into reconditioning Mk 4 hubs!
Another option is you get onto the net and find New Zealand scrap car dealers. You probably will not get any sort of guarantee out of them either.
Regards,
Mr Bean.
P.S. This is my first post, hope I haven’t screwed it up…

without wanting to get myself into a hole I can't get out of, maybe the steering geometry is better, I don't know, but the sierra upright
was designed for a macstrut application and consequently the camber change characteristics are perhaps questionable when a wishbone which pivots is
plonked in place of a strut that doesn't.

If people are struggling to get hold of Cortina uprights, then use some of the plethora of other double wishbone equipped car
uprights...........manta, monza, chevette, viva, granada.........the list goes on and on and they are all pretty similar to the cortina upright.
