A shaft assembly (42) for a gas turbine engine (20) including an outer shaft (46), an inner shaft (44), a lock nut (48), a locking shaft (50), and a washer (52). The outer shaft (46) includes a bore (56) extending between first and second ends. A portion (74, 78, 82) of the inner shaft (44) extends within the bore (56) of the outer shaft (46). The lock nut (48) is secured to the inner shaft (44) proximate a second axial end (74) of the inner shaft (44). The locking shaft (50) includes a body portion (100) extending between a coupling end (102) and a retaining end (104). The locking shaft (50) is disposed within the bore (56), with the coupling end (102) engageable with an end of the lock nut (48). A washer (52) is engageable with the retaining end (104) and the outer shaft second end. In the assembled state, the locking shaft (50) prevents rotation of the lock nut (48).
