When I was working my way through engineering school as a mechanic on
British cars in the early 70s, we saw quite a few failures here, but it was
due to the fact that people didn't lubricate them. After a while, the
upright would seize in the trunnion, and the car would continue being
driven. When finally completely seized, the steering was only through
twisting the upright at the base of the threads, which eventually broke in
fatigue. Keep them lubed and you should have no problems. Remember, these
were used on lots of race cars through the 60's, even F1.
