How To Replace your Lower Column Bearing: Better and Cheaper!!!
Once again the only columns that had bearings were column shift or 1970 with a lock out tube.
Adding a bearing at the bottom on the shaft is not a good idea unless your vehicle came with a rag joint combined with a lower slide joint.
If I was selling this bearing shown on this thread or installed one because I didn't know better . I too would promote them so I didn't feel stupid that I bought one. The top bearing and the bearing in the box is all you need. Putting a third bearing between them will bind the three if column adjustment is needed at the firewall and shimming the column at the attachment will be necessary as they did on the early years.

Before replying watch this rebuild. This is a 70 column with a bearing . But it is only for 70 lock out tube not the steering shaft.
What I have seen on over 30 floor shift columns I have here taken from 70-75 is some remnants of a foam seal. I mimicked it on my column. Note the plastic ring is clipped in place by itself with plastic tangs. I do not have any columns here with a bearing on that ring or a inner race on the shaft. They couldn't all have fell out. LMFAO at some of you
