The steering column bushing finally gave way several weeks ago and since I've had the part for the last three years, I figured it was time to replace it. What made this task most difficult was that I was doing it alone, so pressing the bushing into the 'firewall' proved to be a bitch, but doable. Once I removed the retaining bolt from the U-joint between the column and the rest of the steering linkage I used a cold chisel and a persuader to help seperate the rusted and crusted splines. Then with the help of a giant screwdriver I was able to pry the column out of the joint. Then I had to remove the column mounts from the dash which of course requires acrobatic-like skills (which I don't possess). Once that fell down onto my face I gave the wheel a series of vicious yanks and pulls until it finally pulled the whole unit out of the car. The destroyed bushing and 30 year olf grease of course followed. The new bushing doesn't simply slide into place, it needs to be pressed in, so I made a make-shift bolt press using an old trailing arm bolt and nut and some 1/2" sockets (see picture). Of coruse, trying to get this thing to stay in the firewall from the trunk end while I was working under the dash was a pain by myself, but doable. I then cranked on the nut until it pulled the bushing into place. Then came reinstalling everything, which was just as much of a pain as removing it all. Since it's basically the same as the removal I won't get into all of that.
