Early A Lower Steering Column Seal
I think I got mine from RT Specialties. I have seen big fat o rings listed other places but I don't think they are correct or work that well. I installed mine a couple weeks ago and what a difference it made. No more hot air blowing on my feet and a whole lot quieter too. Wish I had snapped some photos though.
If I were to do it again, I would pull the column, the wheel and the shaft, then re-assemble. I rebuilt my steering coupler also and that cross pin was a booger to get out. I ended up heating it up and driving it out with a air chisel. You have to remove the pin to install the seal because the inner part of the seal is nylon and not rubber. You can't stretch it over the pin. tmm
