  Q: How to replace the Upper Steering Column Bearing on GMC Sierra 3500 Classic?

  A: Begin by eliminating the Steering Column followed by removal of the inflatable restraint steering wheel module coil, turn signal multifunction switch, ignition lock cylinder case, tilt spring, automatic transmission control. The compressor (J 23653-SIR) combined with adapter (J 42137) allow removal of Steering Shaft lock plate retaining ring for disposal. Extract the Turn Signal Switch cancel cam position plate together with the Turn Signal Switch cancel cam and Steering Shaft upper bearing spring and Steering Shaft upper bearing inner race seat and Steering Shaft upper bearing inner race from the Steering Column shaft assembly. Use the pivot pin remover (J 21854-01) to remove the two pivot pins which hold the Steering Column tilt head assembly together. Place the tilt lever into the Steering Column tilt head assembly before pulling back the tilt lever while drawing the Steering Column tilt head assembly downward and toward the Steering Column. First separate the Steering Column tilt head assembly from the anti-rotation pin (J 42640), then remove the tilt lever and the Steering Shaft upper bearing from the Steering Column tilt head assembly. Installing the Steering Shaft upper bearing into the Steering Column tilt head assembly precedes Steering Column shaft assembly installation. Move the Steering Column tilt head assembly toward the Steering Column until the steering wheel lock shoes become secured. Install gm p/n 12346293 (Canadian P/N 992723) on pivot pins then push each pin into the Steering Column tilt head assembly while delivering stakes to three points on the Steering Column assembly. The anti-rotation pin (J 42640) with these components must be attached to the Steering Column shaft assembly: do the following steps when installing parts to the Steering Column shaft assembly: apply gm p/n 12345718 (Canadian P/N 10953516) across the Steering Shaft upper bearing inner race then position the Steering Shaft upper bearing inner race and Steering Shaft upper bearing inner race seat and Steering Shaft upper bearing spring followed by gm p/n 12377900 (Canadian P/N 10953529) lubrication of the Turn Signal Switch cancel cam and complete the installation with the Turn Signal Switch cancel cam position plate. The installation process requires use of the compressor j23653-sir and adapter j42137 for the new Steering Shaft lock plate retaining ring followed by automatic transmission control assembly then tilt spring and ignition lock cylinder case and turn signal multifunction switch and inflatable restraint steering wheel module coil until the Steering Column is installed.
