OOPs are you using extra dowel pins on your hubs?
Nope, just ARP studs from FROR. I do not know why, but I had problems with the ARP knuckle studs from TG. No matter what I did the cone washers were seizeing up on the stud and I would have to remove the stud to get it out. It did not happen on the studs from FROR. Yes I was using anti-seize on them.
Even with the six stud knuckles I check the nuts to make sure they are tight.
