YOu are very wrong, tie rod ends are adjustable for toe in and toe out. and the rear and front should be aligned. When parts are worn or replaced in the suspension or steering, IT is mandatory to check and realigned the suspension and steering gear. The only permanent alignment I have seen is on the little wooden race cars that the cub and boy scouts make for the pinewood derby. It doesn’t mean that cars can hold alignment when a part is replaced, but how do you know without testing and resetting. Part of the cost of ownership and proper maintenance.
