After a trying day with one pinch bolt yesterday, today went from bad to worse The bolt would not respond to the usual techniques so I had to drill it out



This was going reasonably well until the 9.5mm drill bit caught the hardened balljoint pin and snapped off deep in the hole



I had to get the balljoint pin out to go any further. Drilled down the centre of it



Then used a cutoff wheel through the slot to cut it in to pieces



It came out in chunks



I was able to free up the drill bit, although it took a small chunk out with it - that'll get welded up before it goes back together







This upright is bruised around the lower arm inserts as well. So much so, in this case, that the sleeve is now captive



The hubs were quite rusty and rough which could cause wheel balance issues



Cleaned up



Gave up after 6 hours of this and finished early.
