I am trying to replace the wheel studs on my 91-up bolt-in hubs (Timken 513075) with ARP studs, but the old studs won't come out of the hub. The heads of the studs are D-shaped to clear the hub housing, but the heads are not oriented properly and when I attempt to press them out of the hub, they catch on the hub housing and won't come out far enough to allow me to rotate them.

Can the bolt-in hubs be disassembled and reassembled without being ruined, or pulled apart enough to give clearance to let the stud heads be turned to the correct orientation?

Or is grinding the heads off of the old studs the only option?
