The first step in replacing the Steering Wheel is to disable the sir system. Remove the inflator module and the horn switch after that. This leads you to make an alignment mark to remember how the Steering Wheel relates to the
Steering Shaft. Remove the Steering Wheel with the j 1859-a Steering Wheel puller and one of the two mentioned split apart devices, namely j 36541-a or j 42578. Next, line up the marks made before, take the Steering Wheel and place it onto the Steering Shaft, and tighten the Steering Wheel nut to 40 nm (29 ft. Lbs.). Afterward, install the horn switch, the inflator module, and electrify the sir system.
