This is the tool you are talking about? I hate thin wrenches, except for something light weight like a table saw blade.
Thanks for the response Eric,If the problem didn’t start until you put aftermarket balljoints in, start there. They are probably a little too tight . It may loosen up with some miles. You could also go back to a factory joint, see of it smooths out.
your alignment isn’t perfect but it shouldn’t cause it to drive like you describe.
