For those who have mounted bad ARP studs, it may be tough to get them removed as usual extractor are rather short, I did my front yesterday and I was lucky enough to find 2 extractor that 'work together'. See below:
This extractor was clearly too short...
But luckily I had another extractor that I was able to place on top and it works perfectly
I just hope that they will "stick" as the hub are not designed to change studs often. Time will tell.
