Moog Idler Arm Causing Stiff Steering
Rebuilt entire front suspension with moog parts, new bushings ect. The steering box is original and was not touched. All parts have been lubed. Problem is the steering now is very tight and the wheel will not return to center on turns. I'm thinking the problem is with the idler arm because it was very hard to move before bolting it on the car. Asking for any advice to loosen this thing up. Also, I've driven a couple hundred miles and still no change. A picture of me on the dragon tail trying not to die for your time. Thanks

I can't see just the idler arm causing this. I think it may be a combination of things that add up to stiffness your have. Make sure your tie-rods are not binding up.
Did you go rubber or poly bushings?

The idler arm should be quite stiff when new, how about your alignment....Have you got lots of castor in? Did you try moving the wheels manually after new ball joints were installed (before the drag link was installed?)
Another thing to check is the balance of the power steering valve assembly, and possibly a collapsed hose thats blocking flow.

When you changed from power steering to manual steering earlier, did you move the tie rods to the non-power hole in the lower control arms?
This tie rod is in the power steering hole. The other hole is for manual steering and requires less effort to turn (return) the wheels from straight ahead.
Good luck... GUSTO

Replaced with poly bushings. And yes converted to manual steering before rebuilding the front end and the steering was fairly easy to turn compared to now. There is increased resistance turning the wheel with the tires off the ground than before. Good point about the tie rod steering hole however there are no separate holes on the 77. I'll disconnect the idler arm and see if the problem persists to try and localize the issue and will report back. Thanks y'all

Since the steering knuckle arm is a bolt on item, it might be interesting to see if switching to the earlier arms would change the effort required significantly.

I hate to ask this, but... Since all those joints are new, have you greased them? (they don't come greased.)

Turning radius is controlled by the stops on the lower A-frame and the steering knuckle arm (or the tire striking the frame whichever occurs first), not by the distance from the tie-rod and the spindle centerline. The steering wheel effort will change and the turns (lock-to-lock) will change, but not the turning radius.

If there is enough throw to hit the stops. On my friends "put together" 69 there was not enough throw. Never tried it on an original car.
