steering issue

[62bagger]

I have a 65 front x member on my 62 that was installed when I bought the truck. I have 2" lowering springs ant 2" drop spindles. I had the truck aliened, and it feels like when turning the truck wants to dart in that direction. I went back and measured everything on the front end and noticed the pitman arm is 5" and the idler arm is 6". I have found a 5" idler arm from Moog and was wondering if this would correct the problem. Has anyone else has had this issue and how did you solve it. I am trying not to throw too many parts at this and cause a larger problem.

Arm length alone may not address the problem. I would think that mounting locations matter as much as length. To get a definite answer, you may need to establish a centerline and a perpendicular to see where pivot points are relative to each other. Take some measurements and get your protractor out.. Who said we'd never use geometry again?!?

Does it do it on full lock going slow or any time a road speed?

I will look into the pivot points. Thanks for the info.

I notice it at normal driving conditions. At low speed it leaves tire marks on
ground and you hear the tires squealing.

It’s not what I was thinking. I just did a 78 front swap in my 62. If I remember right I had both measurements of the Pittman and idler arm the same distance.
