Had to happen sooner or later I suppose: suspension knuckle snapped

Whats the views to resolve- extract it or replace the hub?

Looking at the rest of it I'd say replace the whole hub.
Simple enough to do.
Then maybe clean up and repair the old one ready for your next bout of hamfistedness. :poke: :D
 
You might get it out with a reverse screw extractor in or your could use a dremel burr and collapse what's left of the bolt in on itself (did this on my sump pan) but probably just as straightforward to replace the whole hub

Cheers James

Got a couple of new hubs lined up for it-

Will be like triggers broom soon
 
If you want to recover the old one at some point try a thinnish drill, very fast. You'll knacker the drill bit but the heat may help loosen it. Then if you use a bigger drill bit, there's a chance you may actually be able to screw it all the way through and out the back.
Worth a try.
Another tip........... this sounds counter-intuitive but sometimes you can crack a bolt by tightening it a tiny bit first.

PS. Don't let anyone every tell you aircraft engineering is all fancy finesse. BF hammers and screwdrivers used as levers all day long. :rofl:
 
Fully expecting the same the other side

And the two bolts on the tie rod and the wishbone are toast too

Angle grinder may be needed

It's a high tensile bolt, it'll be very difficult to cut / drill out.
 
That is quite some rust!

The same happened to me. I welded a nut on the other side and was able to get the rest of the bolt out. First I cut the middle part of the bolt, which is visible, away so the rust does't need to go trough the thread. I had to get the whole hub on the bench to get the rest of the bolt out. You should be able to get the shock absorber out because there is no clamping force anymore.
