Alignment problems

I have a mystery I hope you can solve for me. I currently own a 1989 Dodge Ramcharger 2wd, with a 360ci motor. The problem is that when I drive the vehicle the wheel is always angled between the 10 o’clock and 11 o’clock position. It also seems that the faster I go the more angled I have to hold the wheel. Ex: 35mph I have to hold it around 11 o’clock and 55-65 mph I have to hold it around 10 o’clock position. Another interesting note is that the wheel, when braking, some times comes back to the 12 o’clock position but back to 11 o’clock again when I return to the gas.

I have been to three different mechanics in town and can’t seem to get a correct answer. Two mechanics have said all I need is an alignment job, which I had done both times to no avail. The third mechanic said I needed a new idler arm followed by an alignment, which I also had done. But again with no luck.

In the last year I have replaced the following items trying to fix the problem: new power steering pump with lines, new brake calipers, pads, brake lines, front rotors, new brake shoes, shocks all around, and the following moog suspension parts both inner and outer tie rods, both upper and lower ball joints, drag link, and the idler arm. I have also replaced the steering gear box, but for other reasons. I have checked the strut rods and they are tight and also the u bolts that hold the axle to the leaf springs and those are tight also.
