blacksheep-1 replied to the thread Pulling Axle - What’s Needed.Just to drive you crazy, on project superbeater I had all the axles n hubs out, pressed the studs in and then mounted an old wheel on them to insure they were straight. I then tack welded the studs in while the wheel was mounted. Total overkill... (see full post)
