"Lumpy" Steering on 1970 Dart Swinger

Hello,

It has been a while since I last posted anything on Forabodiesonly! A lot has happened in the meantime.

I last year, I dropped the steering column to replace the ignition switch and its wiring harness. When I reassembled the column, and test drove the Dart, I found that the steering was "lumpy" when I was turning the wheel to and from center. When the tires are straight, and I turn to one direction, the steering is smooth and easy, but if I return from one side to the center I feel resistance in the steering wheel. Its not super heavy, but it takes noticeable effort to turn through the "Lump"

When I dropped the steering column and took it all apart to replace the switch, I could feel the steering shaft pull in and out, but it was captive. Does this affect anything?

My car has the 198 Slant Six and has a power steering system. I noticed yesterday that I had a small power steering fluid leak from the box, running down the Pitman Arm.

Thanks!
