TR2/3/3A 1960 TR3a front suspension

I am hoping to get some input about the trunnion workings?
Had the car in for motor vehicle inspection and the mechanic
did the usual pry bar front wheel lift and we noticed the trunnion
had a slight rotation when lifted and he wanted me to check into this?
Should the lower end and trunnion move up and down without any rotaion?
I drove car for 3 hours on highway to get it home and steering was tight without
any vibration or play. I really enjoy reading the posts and a great forum for
triumphs. Thanks Dave.
car passed and is now legal

If I understand you correctly, it sounds to me as if the trunnion is doing exactly what it is supposed to do...and all is fine!

As Andy says, the trunnion should rotate when compared to the lower A-arms. But it should not move in that axis relative to the vertical link. If you can see the vertical "barrel" of the trunnion twisting in or out, then there may be excess wear between the trunnion and the threads on the vertical link. Not usually a common problem, but it happens sometimes (usually corrosion due to long neglect).
