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.
