Question type: Maintenance & Repair

Replaced idler arm thinking that was the
problem. (was in really bad shape) power
steering is fine nothing under front end is
sloppy. Lower ball joints squeak a little,  
don't think it related though. it is really
dangerous to drive,  it I had to swerve really
fast,  there is no way I could keep it under
control. Feels like it yaws if we have any
pilots here. Replaced tires twice,  but didn't
help.  Any help would be greatly

Yes sir, everything is tight checked for movement in the wheels while they were in the air. Did notice today that if I make a turn and let go of the steering wheel, car will not straighten, just keeps on turning. I also did a rear suspension conversion a few months ago. At bags went and replaced with a coil spring kit. Not sure if that matters.
