i dont think you have to have them "pressed" in? i just swapped my original studs for longer ones(damn offset!)gave me an extra 3 inch thread i needed to mount the wheels my client wanted on the el.ive also done this(replacing studs) on a couple of my 4x4's,and all ive done is install them from the back side of axle flange,snug up original lugnut and set in place by using cresent,channel locks and turning clockwise(tightning)them enough so that they stay stationary.now with them set momentarilary i back off the lugnuts,mount rim/tire then install lugnuts(closed end specialty nuts)and tighten so that nuts are pulled through/set flush with axle flange.hope you had a good day,and drank some of that good beer(the kind other people buy :wink: )staying glued to my laptop for the progress report
