I am trying to replace the steering wheel speed sensor. I have removed the bolt that holds the upper and lower portions of the steering column. However, I can only push the lower portion of the steering column down about a half an inch. I have tried to wiggle it down and apply muscle but have not had any success. Any guidance or tips would be much appreciated on how to completely separate the lower and upper portions of the steering column so that I can change out the steering wheel speed sensor. It is called the "steering wheel speed sensor" or the "sensor assembly, steering wheel speed". I believe the picture you provided is only a partial one. If you look at the full image toward the bottom, you should see the steering wheel speed sensor identified. I am not an expert but I believe the lower portion of the steering shaft assembly I need to move might be called the "intermediate steering shaft". Thank you.

If you pull the steering column shaft from the column you will wreck the clock spring. I think you mean the EVO sensor, which you pull the intermediate shaft then pull the column. See picture. We have no instructions on that however. The bolts could be bolted to floor.

Yes, the EVO sensor is what I would like to replace. Unfortunately, I cannot get the intermediate shaft to pull back into the firewall far enough for me to replace the sensor. Per some YouTube videos I have seen, apparently, the intermediate shaft slides into the firewall but none of the videos actually show anyone doing this. They just show before and after. Hopefully, someone has encountered this situation and has figured out the trick and can share. Thank you again.

Remove screw on top and bottom of intermediate shaft then tap the bottom half of shaft up then remove it from column you may be able to gain access to the part you want to remove then. Try some penetrating oil and tapping lightly with a small hammer if it doesn't want to move to let oil soak in.
