Good afternoon guys. I just replaced all 6 of the subframe bushings on my 68. No problems at all getting old ones out and new (GM reproduction rubber mounts) installed.
However now that the new bushings are installed, it seems my steering column is binding at the 10 and 2 position when turning the wheel. I checked the alignment of the subframe and loosened and retorqued the bolts in the correct sequence, all to no avail. I replaced them with the car on the floor and used the 2x4 method under the body to raise it off the subframe. For the life of me I can't figure whats different to cause this. The steering was perfect before. The rag joint is not damaged, the steering box is in the same position (it didn't move) but now the shaft from the column is rubbing on the firewall coupler (where it goes into the firewall)
anyone ever see this and have any suggestions?

 

Body lines and gaps between fender(s) and door(s) the same?
When viewing from the side, does the bottom of subframe parallel with rocker panel?
You may have to add a fender washer between the body and top bushing, all four of them.

 

Thanks for the suggestions on where to look Everett#2390. The body panels are perfect, and I checked the subframe index holes (where the body has a hole in it to line up the subframe with a pin) and those are spot on as well. Ill experiment this weekend with adding a washer to one side or the other (or all 6 points if needed).
I appreciate the help and let you know what happens. sorry for the giant pictures, ill figure that out too.

 

Yes, reflections look straight.
Maybe drop/loosen column bolts and allow self-alignment then add/subtract shims?
