Caution

During steering wheel bolt removal, observe the following precautions: Do NOT use heat on the steering wheel bolt, steering wheel, or steering column. Using heat could cause damage to the steering related components. Do NOT hammer or apply excessive downward force on the steering wheel bolt, steering wheel, or steering column. Hammering or applying excessive downward force could cause damage to the steering related components.

Note

Steering wheel bolts installed during manufacturing require high torque efforts to remove. The ONLY acceptable bit for removing and installing the steering wheel bolt is a T50 Torx bit. Do NOT use any other size bit or a worn bit. If a power tool is used to remove the steering wheel bolt, the tool must have a minimum torque rating greater than 75 Nm (55 lb ft) and both the power tool and the T50 Torx bit MUST be positioned perpendicular to the bolt recess. Apply appropriate downward force to maintain engagement of bit to bolt recess during bolt removal.

7. Loosen the steering wheel bolt (1) so that 2 - 3 threads are engaged.
8. Wiggle the steering wheel until the wheel disengages completely.
