Steering Wheel, Gray

Disabled sir system operations should occur first before turning off ignition power. Align the inflatable restraint Steering Wheel hub with the slash cut on the Steering Shaft then mark it with a scribe. Using an appropriate tool loosen the Steering Wheel nut until it reaches the end of the Steering Shaft. Place the j1859-a Steering Wheel puller (J42578 Steering Wheel Puller Legs) around the Steering Wheel to unseat it from the Steering Shaft. Remove the puller from the assembly then remove the Steering Shaft nut to detach the Steering Wheel from the Steering Shaft. Remove the sir connector from its position on the Steering Wheel. To put the sir connector in position pass it through the Steering Wheel then match the scribe mark with the slash mark found on the Steering Shaft before setting the Steering Wheel. First tighten the Steering Shaft nut to 45 nm (33 ft. Lbs.) before reinstalling the inflatable restraint Steering Wheel module and reactivating the sir system. The inspection process needs to verify the proper operation of the Horn and Steering Wheel in addition to Steering Wheel controls.

To remove the Steering Wheel, first, disable the sir system and put the ignition in off position. Take off the inflatable restraint Steering Wheel module and scribe and alignment mark on the Steering Wheel hub to this mark, align it with the slash mark lying on the Steering Shaft. Loosen the steering-wheel nut, and seat it flush with the end of the Steering Shaft. Fit the j 1859-a Steering Wheel puller (J 1859-A) onto the j 42578 Steering Wheel puller legs (J 42578) connected to the Steering Wheel and use this assembly to dislodge the Steering Wheel from the Steering Shaft. Remove the Steering Shaft puller, Steering Shaft nut, and Steering Wheel, and also un-route sir connector from the Steering Wheel. For the installation, route the sir connector through the Steering Wheel, align it with the slash mark on the Steering Shaft, and put on the Steering Wheel. Fasten the Steering Shaft nut with 45 nm (33 ft. Lbs.). Install the inflatable restraint Steering Wheel module and turn unpaved the sir system. Finally, check the horn, Steering Wheel, and Steering Wheel controls.

First, you need to turn off the ignition, then disable the sir system in order to replace the Steering Wheel. Remove the inflatable restraint Steering Wheel module and scribe an alignment mark on the Steering Wheel hub aligning it with the slash mark on the Steering Shaft. Loosen the Steering Wheel nut and place in on the end of the Steering Shaft. Attach the j 1859-a Steering Wheel puller (J 1859-A) along with the j 42578 Steering Wheel puller legs (J 42578) to the Steering Wheel and then use this assembly to knock the Steering Wheel off the Steering Shaft. Pull off the puller, Steering Shaft nut and remove the Steering Wheel and unroute sir connector from the Steering Wheel. For installation, yon route the sir connector through the new Steering Wheel and align the scribe mark with the slash mark on Steering Shaft then install the Steering Wheel. Mount the Steering Shaft nut after tightening to a torque of 45 nm (33 ft. Lbs). Lastly, install the inflatable restraint Steering Wheel module and activate the sir system and inspect on the history of the horn, Steering Wheel, and Steering Wheel controls.

Remove the steering shaft nut and the steering wheel, followed by the SIR connector from the steering wheel.
