From where comes the lower ball joint and the lower wishbone's bushes of a Sierra based Striker?
Very dangerous, fortunately it happens on a straight line at low speed.
From where comes the lower ball joint and the lower wishbone's bushes of a Sierra based Striker?
I got one from raw recently, think it was about £18 delivered. Didn't know what it was so just went to them.
Hope the damage is minimal?
Yes, only the lower wishbone but if it happened on the twisty roads I could have gone like a rocket on the mountain or down into the canyon.
Did it break on the weld? Any undue stress (pothole) or just completely random? Got me paranoid now 
Seems on the weld but I've to check better.
Completely random, just apparently normal corrosion.
glad you're ok. hope it wasn't the same person who welded the wingstays.............Mr Pigeon Chit...
Deffinately checking mine thoroughly before the next outing!
Glad all ok otherwise.
What diameter is the tubing?
If I remember correctly 19 mm of diameter, 1 mm of thickness.
I would like the next wishbone to be 25 mm of diameter with 1.6 mm of thickness.
Happened on my Phoenix but then they where 19 years old when they let go. Raw have them I'm sure.
I sent a mail to RAW
They're a maxi joint IIRC
Is that a part originally manufactured by Sylva Autokits or RAW engineering?
Don't really know.
I was never happy with using the small round bar I had my Locost ones remade in oval tube as the originale started to bend
That's why on the F27 I went for 25mm diam and 3mm wall thickness tubing.
Suspect it only adds marginally to the car's overall weight but gives a better sense of security.

Make sure you also replace the other wishbone, probably on it's way to failure too.
How much castor has your front? If it's too much it might give stress on the bottom balljoint under load and thus stress on the wishbone.
Yes, I'll replace also the other.
A lot of castor, more than 10 degrees.
On a trackday i have seen lower wishbones bend back after heavy braking. Reason for some to box up the tubes, so much like the upper wishbone.
Isn't that the same corner you have been working on recently, as in your"which upright" post?

Please tell me there not people out there making lower wishbones for road use from 1mm tube?
It's possible that I don't remember correctly the thickness...I will check!

On looking at your broken tube photo.. there is Rust ! visible on the broken end.
Unless you parked it in the rain for days before taking the photo, that thing was Pre-broken, for ...some time... previous.
Frankly it's a Bodge design .. But inept welding played it's part ?

19mm 1mm wall! I've got stronger curtain poles in the house!

Definately not a Maxi joint from the pictures. There is a large hex visible on the ball joint body so it seems they may be screwed into the wishbone/upright adapter which would make the Metro balljoint a strong possibility.
A plate welded across would stop individual pipe stress at the welds
Something similar to those found on 7's
As has been pointed out, that is a Metro balljoint at the bottom, not a Maxi.
I've just uploaded a typical Sylva/Escort/Capri front set up (on my car) for you to compare. Mine has a lower rose joint, attached by a through
bolt. The bottom of my Escort upright isn't a taper fitting, it's a very crude stepped hole, it your's is the same, then a taper joint
is probably inappropriate - it isn't going to locate properly? It may even bind??????
OK - I doubt that Sylva (Jeremy Philips) if he built the wishbone would use 1mm tube! Sylva were agricultural in the extreme, the bushes on my
wishbones are simply vast, secured by 13mm bolts(!) The wishbones themselves are boat anchors. Sylva weren't subtle.
1mm tube is simply not what should be there, destroy the wishbones and make new ones now if they're all like that. Do it now
As I said, maybe I don't remember correctly the dimensions of the tubes and possible they are bigger and thicker...I'll let you know.
I'm going to measure it tomorrow, now the car isn't at my house.
Looking at Google images, the balljoint seems to be the Metro one as suggested.
Thanks everyone.

If you post a biggish picture on showing the fracture surfaces and picture of the undamaged wishbone there are plenty of people on the forum who
can give some insight as to how the failure initiated. On the face of it looks like a weld with a significant flaw acting as a stress raiser
leading to a fatigue crack which grew to the point of sudden brittle failure.
With welded joints like that the devil is in the detail of the design, blindly using bigger or thicker tube or welding on random fillet plates
isn't the way to go, any modification should be carefully thought out to avoid introducing a new point where failure could initiate.
I confirm the diameter of 19 mm and the thickness of 1 mm.
Well as it was the weld that failed I would suspect that the size wouldnt be the cause, however that does seem rather underspec. How well do you know the history, could it be that its had a replacement made for it outside of the OEM spec?
Don't know, many owners before me.

Thanks for posting, I will be checking mine, glad car and you are ok.

Looks like mine are uprated luckily
