  1. Remove the nut (3).
  2. Disconnect the horn ground lead (5).
  3. Notice: When removing the steering wheel, use only the specified steering wheel puller. Under no conditions should the end of the steering column shaft be hammered on, as hammering could loosen the plastic injections which maintain steering column rigidity.

    Notice: When attaching J 1859-A and J 38720 to the steering wheel, use care to prevent threading J 39720 (bolts) all the way through the steering wheel hub into the SIR coil and damaging the SIR coil.

Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener.
