Re: 78 GMC Steering column

i Just did this yesterday morning and I will say it is one of the more frustrating things to do. First question is are you working on a tilt or non-tilt column?

On a non-tilt I think the two places it can be off are misalignment between the actuator rack and the gear that the ignition tumbler slides in to. When it’s put together the rack has to be on the right tooth of the gear or you won’t get full exension of the key (either it won’t go into ACC position or it won’t turn all the way to start).

The second place is down at the ignition switch. The switch has oval holes which allows for minor adjustment up or down to correctly engage. There isn’t a lot of adjustment here.
