Pitman arm question
I got a new power steering gear box and pitman arm for my 69 (no-buck). It has 73+ upper and lower control arms on it. I got the whole front suspension from a donor 72 suburban that obviously had been swapped in there as well. So I don't know what is what. The partnumber that I removed is 6272424.
So tonight I got to put in my new pitman arm and gearbox. Well come to find out the pitman arm that I installed (ordered it for a 73 C-10) is shorter than the one I removed. The partnumber that I removed is 6272424. Now, when I steer all the way to the left, the spindle doesn't quite hit the stop. Turning right it does. Looking around at stuff it looks like the tie rods could be adjusted so that the left spindle would hit the stop, but I didn't want to mess up my alignment. But having the shorter pitman arm, is it already messed up? Should I install a 72 pitman arm, or just stay with the 73? What do y'all think? |

Re: Pitman arm question
The shorter arm will just make the ratio faster.

Re: Pitman arm question
well I bit the bullet and got another new pitman arm for a 72. Looks like it will work fine and I'm back in business.

Re: Pitman arm question
So the 72 pitman arm is longer than the 73 and yet the 72 arm fits the 73 box?

Re: Pitman arm question
That appears to be true. I bought a 72 pitman and it fits the 80's steering box I bought and mounted on the 72 frame with the 72 tie rods/etc. ( I bought the 80's box for the metric fittings for the 5.3 I installed.)
Whether the 73 pitman is shorter I can not comment.

Re: Pitman arm question
It would be nice to confirm if the 72 pitman arm is longer. Longer pitman arm equals better turning radius.

Re: Pitman arm question
Has anyone ever confirmed if the 72 pitman arm is longer?
