Striker front lower wishbone failure
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.

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.

Is that a part originally manufactured by Sylva Autokits or RAW engineering?

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
Life is like a bowl of fruit, funny how all the weird looking ones are left alone

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?

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.

It's possible that I don't remember correctly the thickness...I will check!

Yes, but over a year ago, working on both corners and not a problem at all with a few miles on the road and a couple of trackdays.
I think the main problem was the rust inside the tube.

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 ?
