I had some Arp 1/2" studs pressed into my rear axles and front hubs, and almost all have a small space between them, just about where i can almost slide a razor blade behind them. i tried to re-tighten all of them and they seem to be bottomed out where they cant go any further? is this an issue? will they seat when i start to drive the truck and re-torque the wheels? the truck is not running or driving yet so this is not urgent, id just like to figure it out.

Thank you.

Hmm...were the holes resized for the proper .005"-.008" interference fit? You definitely want the heads seated firmly against the inboard face of the hub and/or axle flange, otherwise they can and will loosen during use, and a loose stud is often a broken stud in short order. If you paid someone to press them in, I would be talking to them first since that's not right IMO.

Knock one out and check the hole for a chamfer to match the radius on the underside of the head. If the holes were re-drilled adding the chamfer may have to be done to get the bolt to seat correctly.

i ended up going over the rear studs with tons of washers and anti seize and a 1/2" impact. they are all seated well now from what i can see, just took some time. the fronts i am going to go over again with the hydraulic press. thanks guys!!

After you first drive the car, recheck the torque. You should do that a couple times a day for several days just to be on the safe side. If you autocross, you should do it after every run for a few events.

I had that problem with moroso studs and aftermarket axles. I had to take it down to a machine shop and have them pressed in.
