[DeTomaso] Spinning wheel stud

Sun Jul 15 20:57:00 EDT 2018

Another thought. The flat on the stud prevents rotation when the stud is fully seated. If the stud is allowed to fall back out of position slightly, the tapered shoulder of the inside of the rotor hat no longer engages with the flat edge of the stud and then it can rotate. 

Since you have ready access to the back side of the stud, rotate it so that the flat is in the proper position. Then use a hammer and punch and fully seat it. With somebody holding pressure on the punch to keep it in place, the flat might have enough engagement to allow the nut to be turned at that point.
