I was successful in removing the roll pin on the steering rack to steering intermediate shaft. It is important that you remove the steering column coupler first
(under steering wheel). This will provide enough slack for the shaft to extend past the dash panel seal & boot.
It is a tight spot to use the punch and hammer, but with a helping hand I was able to knock it out. We used a 1" open end wrench to hold the flex joint stable and i placed a small block of wood under the steering rack to absorb the shock. The punch size required is 1/4", although I started with a slightly larger punch until the roll pin began moving.
Putting the roll pin in also requires the same technique. I suppose one could actually design there on roll pin removal tool with the nuts, studs and bolts.
