24) Install the instrument panel side cover LH in reverse order of removal.
25) Install the steering column upper cover and steering upper cover in reverse order of removal.
26) Transfer steering wheel components to the new steering wheel and install to the vehicle.
a) Remove and discard the screws from the paddle shift switches (models with paddle shift).
b) Remove the rear steering wheel cover by carefully prying near the 4 clips. Remove the rear steering wheel cover and the paddle shifters as a unit.
c) Remove the screws, and then remove the satellite switches and the center steering wheel cover.
d) Transfer the center steering wheel cover, satellite switches and rear steering wheel cover to the new steering wheel. Observe wiring routing to ensure wiring is secure in all clips and is clear of any metal edges.
e) Install paddle shifters to the new steering wheel using new screws.
Tightening Torque: 1.7 N~m (0.2 kgf-m, 1.3 ft-lb)
f) Verify correct routing of the satellite switch wiring harness to prevent interference with the dynamic damper (DD) to be installed in the next step.
g) Install the Dynamic Damper (DD) to the new steering wheel. Do not allow the wiring harness to interfere with the DD. Make sure there is a minimum of 5mm clearance between satellite switch harness and the dynamic weight of the DD on all sides.
Tightening Torque: 1.7 N~m (0.2 kgf-m, 1.3 ft-lb)
CAUTION:
It is crucial that the wiring harness does not interfere with the DD.
h) Install the new steering wheel.
Tightening Torque: 39 N~m (4.0 kgf-m, 28.8 ft-lb)
i) Connect electrical connections to the roll connector and secure the harnesses together with electrical tape, as seen below.
Note:
Vehicles not equipped with paddle shifters will not have harness marked (A), seen below.
j) Install the airbag module assembly in reverse order of removal.
Tightening Torque: 10 N~m (1.0 kgf-m, 7.4 ft-lb)
k) Position the tilt function to the center of the travel; this will put the steering column in the proper position when tightening the universal joint bolts later in the procedure.
27) Disconnect the air/fuel and oxygen sensor connectors and remove the clip which secures the harness
28) Raise the vehicle on a lift.
29) Remove the engine under cover and front exhaust pipe.
30) Replace the steering gearbox sleeve spring (supplied with Chassis/Hardware Kit - Part number 34190A1021).
a) Remove the steering gearbox bracket bolt.
b) Loosen the lock nut using ST 34199A1050.
c) Remove the lock nut, adjusting screw; spring and pressure pad from the gear box.
d) Thoroughly clean the adjusting screw and surrounding surface on the steering gearbox to remove any dirt, grease or old sealer. Apply a small amount of Three Bond 1215 (SOA # 004403007) to the adjusting screw threads and spread around by hand.
Note:
Use only Three Bond 1215 (SOA# 004403007). Use of other sealing products will affect reinstallation of adjusting screw.
e) Apply a coat of grease to the sliding surface of the pressure pad and the seating surface of spring, and then insert the pressure pad into steering gear box.
f) Fill the inside of the adjusting screw with grease and insert the spring into the adjusting screw.
g) Install the adjusting screw and new spring into the gear box and tighten the adjusting screw to the specified value, then loosen it one rotation.

i) Reinstall the lock nut and tighten by hand.
j) Use a socket to hold the adjusting screw in place to prevent it from turning while tightening the lock nut with ST 34199A1050.
Note:
if the adjusting screw has moved~ the procedure will need to be performed again from the beginning.
k) Install the steering gearbox bracket bolt.
Tightening Torque: 60 N~m (6.1 kgf-m, 44.3 ft-lb)
1) Relieve steering column universal joint preload and tighten the universal joint bolts.
NOTE:
Verify the steering column tilt is adjusted to the middle of the travel before relieving universal join preload.
1) With the universal joint installed, but with the bolts still loose, grasp the universal joint (C) and move it up (toward the steering column) and down (toward the steering gear box) a minimum often times, ending at the steering gear box side. This will eliminate any unwanted preload on the universal joint.
NOTE:
This step is critical for a successful repair.
m) Torque the universal joint bolt on the gearbox side (B) first and then the steering column side (A).
Tightening Torque: 24 N~m (2.4 kgf-m, 17.7 ft-lb)
Note:
Always torque the universal joint bolts in this sequence; otherwise the universal joint will become preloaded.
