Technical 1.2 Fiat 500 oil pump noise?
What's the chances of the arm being "poor quality " and the taper not being correct and that's why the hub fixing cracked, note the top of the hole is rusty when it should be fairly clean?
I didn't spot that the casting had fractured.. Then realising the pin had dropped with the M8 Bolt still in place I realised there was a failure of the pinch arrangement
As others said.. Probably from overtorqueing that bolt
Wow that's Pretty impressive not seen that done before if definitely go with haven been overtightend
Over tightened sump plug? that might support the theory that the pinch bolt was overtightened by previous owner?
I've just realised the "crack" is a shadow
Yes but it had me worried for a minute!
There was another loose bolt on the sub frame the has to be removed to replace the wishbone so on top of the pinch bolt being mullered I got paranoid and removed everything just to check all the bolts were tight. It was ok in the end but it did mean removing the front bumper again 
I think the issue is that the pin hasn't been fully reinserted after (I presume) the previously perished boot was replaced. That groove on the pin shouldn't be visible, but the very top few millimeters of the bolt should be visible protruding from the pinch/clasp bit on the wheel side (these are professional, technical terms you realise).
The bodged metal clip not properly closing off the top of the boot is a fair pig's ear of a job too.
Apologies if I've entirely missed the point.
Absolutely no apologies needed. It's this sort of post which I always find interesting. Also very difficult often to judge and asses the situation from pictures alone when, if you could see it in the flesh, it would be immediately apparent what's up. Just so glad for you that the resolution didn't involve lots of cash!
Try these people: https://www.biggred.co.uk/ Their inventory is pretty impressive and friends have bought from them and been pleased.
Buy new pins they will come with clips, or a "fitting kit" will also have new stainless pad spring-anti rattle
@gadb you're correct in that the pin wasn't fully inserted through the hub, the bolt was then hammered through which is why the threads are mashed. It was a whole new wishbone with the ball joint already fitted by the look of it.
The clip on the boot was me prodding it about before I took the photos
that went back on easy enough.I've used these guys before and they're pretty good!
Thanks Dobbslc, that's really useful to know.I've used these guys before and they're pretty good!
Seems like a fairly dangerous state for someone to have left the car in. Good thing you spotted it. I had an advisory on my MOT regarding a perished boot, which I replaced although I'm wishing I'd used one of those screw type splitters rather than a pickle fork (which deformed the metal where I'd applied the leverage). Fortunately for me my ball joint had no play in it that I could discern so I didn't put a new wishbone in. I may live to regret that, I'm not sure. Was about 6 months ago and no problems so far. I think the pinch bolt is supposed to be a one-time-use thing according to the manual. It didn't say anything about not hammering the threads off it though, so maybe this is ok@gadb you're correct in that the pin wasn't fully inserted through the hub, the bolt was then hammered through which is why the threads are mashed.
