There isn't enough material for a heli-coil to work properly, however a Time-sert might hold. 14MM x 1.5 thread
A new hub lists for $50. you also will need a new front wheel bearing( $61.) as it will be damaged when the hub is removed.
I have a snap-on tap 14mm x 1.5
Could I not try just rethreading this bolt hole?
It doesn't look terribly messed up - it just looks like a few threads inside got stripped right at the beginning part. I understand any advice is taken at my risk and absolve anyone of any liability!
