Too remove the upper cover the tumbler assembly must be out. As stated earlier this column uses a bolt to retain the tumbler. I will try to come up with a picture of the early style tumbler later.

This is the cover off showing the guts of the tilt knuckle You can see that the knuckle is way off center in this photo, its caused by the bolts that hold the knuckle onto the column being loose.

With the cover off you can remove the spring that loads the tilt mechanism, I use a screw driver. Quarter turn and the cap and spring come out. Shown upper center is the tilt pin remover installed to pull the pin out, there are two of them.

With the pins and spring removed you can install the tilt lever and pull on it and the black part shown will lift off. Pay attention to how the rack fits into every thing. The rack is shown still laying on the lower part of the knuckle, disengaged from the pinnion

I think my '73's key tumbler is held in place with a pin instead. Other than that, looks the same to me.

If this all looks like too much there is a place in Rochester NY called "stolenandrecovered.com" that repairs and rebuilds columns. His name is Doug and he's a great guy to work with. He repaired my tilt and was fast and reasonable.

Here's a few tips.
The tail from the ignition switch/key tumbler is a AMC specific part. The metal rod that goes into the ignition switch/mounted on the column. . They are just a little longer than those used on Non Tilt versions AND GM vehicles. I'm working from memory, but I think the GM cars had 6 teeth and AMC used 7, or vic versa. Also, Tilt and Non-Tilt ignition switches are different, so don't mix them up. The key buzzer is different from tilt and non tilt versions. I have/had complete rebuild photos of both types, BUT the first computer was stolen, then dropped and I haven't been able to get anything out. Then, the MAC hard drive died. So, I', going to look thru the digital cards and HOPE I've got photos. Always make back ups Great thread thus far, Thanks!!! |

If nothings broken in your column this is about as far as you will need to tear it apart. The most common proble is that there are 4 bolts that hold the lower part of the knuckle into the column and they come loose, 2 of them can be seen in this photo, take them out one at a time and locktite them back in place. In order to remove this piece you need to remove the center shaft from the column. Its held in by the bearing at the lower end, take the bearing out and the shaft will pull out.

The upper part of the column will twist and come off fairly easy. Tis gives you better access to the bolts to tighten them. Pay attention it will fit two ways when you put it back on only one is right. On the end by the threads it has a small mark that should be up, it aligns with a mark on the steering wheel.

If you take the lower bearing out of the column the center shown to the right of picture will come out. With the steering shaft out and the four bolts out the base to the knuckle will come off
