7. Pry off retaining ring.
8. Shaft lock.
9. Turn signal canceling cam assembly.
10. Upper bearing spring.
11. Turn signal to right turn position (up).

14. Screw and signal switch arm.
^ Let switch arm hang freely (tilt option equipped with cruise only).
15. Screws, turn signal switch.
^ Let turn signal switch hang freely.
16. Remove coil assembly connector shroud.
17. Steering column support bracket bolts.
18. Upper steering column bolts.
19. Wiring protector.
20. Connect a length of mechanic's wire to coil assembly terminal connector to aid in reassembly.
21. Gently pull wire harness through steering column housing shroud, steering column housing and lock assembly cover.

INSTALL OR CONNECT

NOTICE: Ensure all fasteners are securely seated before applying needed torque. Failure to do so may result in component damage or malfunctioning of steering column.

1. Connect mechanic's wire to centering coil assembly connector.
2. Gently pull connector through steering column housing shroud, steering column housing and lock assembly.
3. Remove mechanic's wire.
4. Install wiring protector.
5. Install connector shroud.
6. Connector centering coil assembly terminal connector.
7. Steering column lower support bracket to steering column.
^ Tighten bolts to 27 Nm (20 lb ft).
8. Steering column upper support bolts.
^ Tighten bolts to 27 Nm (20 lb ft).
9. Turn signal switch assembly.
^ Tighten bolts to 3.4 Nm (30 lb in).
10. Signal switch arm (tilt steering column only).
^ Tighten bolts to 2.3 Nm (20 lb in).
11. Hazard knob assembly.
12. Multifunction lever.
13. Turn signal canceling cam assembly.
^ Lubricate with grease, synthetic (service kit).
14. Shaft lock.
^ Inspect shaft lock retaining ring for damage or deformation. Replace with new retaining ring.
15. Shaft lock retaining ring. Line up to block tooth on shaft using J 23653-C to compress shaft lock.
^ Shaft lock retaining ring must be firmly seated in groove on shaft.
16. Spacer shaft lock (standard column only).
17. Ensure coil assembly is centered.

Important: Assemble pre-centered coil assembly to steering column. Remove centering tab and dispose.

Important: Coil assembly will become un-centered if:
a. Steering column is separated form steering gear and is allowed to rotate.
b. Centering spring is pushed down, letting hub rotate while coil is removed from steering column. In the event this occurs, refer to "Centering Coil Assembly."

18. Coil assembly using horn tower on canceling cam assembly inner ring and projections on outer ring for alignment.
19. Coil assembly retaining ring.
^ Ring must be firmly in groove on shaft.

Important: Gently pull lower coil assembly wire to remove any wire kinks that may be inside column assembly. It is absolutely critical that you make sure there are no kinks or bends in the SIR coil assembly wire. If a kink or bend is present, interference may occur with the shaft lock mechanism. Then turning of the steering wheel may cut or damage wire.
