I read one of Jim O'Shea's articles on Corvettefaq.com about rebuilding columns. I wasn't aware at that time of this article ...probably 3 years ago. Although I was somewhat interested in rebuilding my 70 Tilt column, I just at that time didn't want to do all the work...However, I did decide to replace the lower most bearing on the steering column. It was relatively easy.....glad I did.
The lower bearing was in terrible condition. The waxy lubricant was almost all gone and it was very dirty. Also there was a lot of rust and corrosion. Although my 70 is a California car, I do believe it has had some exposure to salty roads. The 70 lower column bearing was readily available and I replaced it. I would like to do my 68 also, I think it is in much better condition, however the 68 lower column bearing is not readily available.
...............
To seat the bearing into place, I bought a piece of copper plumbing pipe with a diameter equal to the outside race diameter of the bearing.The copper pipe wall was about 1/8 inch thick so it was a perfect tool. However, a 1 foot section of this pipe cost about $25...copper is expensive!!
