Finishing a restoration on a 69 400, 5 speed. Trying to get out some bugs. Replaced and rebuilt everything in steering including ball joints, bushings, pittman, Idler, link etc. Brand new gear box. Replaced bearings in steering column. Wheel bearings are new of course. New tires balanced. Had alignment checked twice by old school rack. (Place has done all my first gen, f body alignments in the past without a problem). Pump is new. Even tried adjusting the allen head in and out... Problem is the car wanders at higher speeds, say 40 mph and up. Not enjoyable to drive because your fighting it all the time to keep it going straight down the road. Been working on f bodies forever and I'm just missing something, somewhere. Thought I might ask the firebird gods here for help. Anyone ever had this issue before? I'm kind of leaning toward a problem in the PS somewhere. It's almost like the PS is working too well but that could just be my imagination. All comments appreciated.
