This evening's pinch bolt removal went rather better.
Start off like this again:
then keep winding the nut and it pulls the bolt out of the hole. Add more washers and carry on
Cut a couple of cm off the bolt otherwise it gets stuck on the steering arm, and repeat the process
Eventually the bolt will start turning with the nut. At that point it can be punched out
(there's a prize for whoever guesses who was keeping me company in the workshop tonight btw
)
Both uprights are ready to be cleaned up and re-fitted so I put the new control arms on.
CV boots on both front shafts tomorrow then put the uprights and brakes back on.
