I'm helping my friend with his 65' convertible. It has been sitting for a few years because of a problem with the steering. It has manual steering. The steering wheel has about 1/8th of a turn of play before it actually starts turning the wheels. I tried adjusting the screw in the top of the box but that didn't seem to help, just made it harder to turn. It also squeaks once you get past the play and start to turn the wheels. The squeak sound comes straight up the steering column to the steering wheel. Almost like it needs grease in the box. What could be causing these problems? Does it just need a simple rebuild or is a new steering box in order? How hard is it to get the box out on the 65'? It seems like the steering column and box are one piece. Any help will be greatly appreciated.
