Many years ago, I worked in a tire shop. Our alignment man would always tell potential customers that their front end was a piece of crap if there was any slack in any of their parts - loose tie rods, ball joints, control arms, etc. in an attempt to sell them on necessary repairs.
I believe that he lost more business because he had no flexibility. He always told them there was no improvement possible until they replaced all worn parts. Most of these potential customers left as they were not ready or able to spend the $$$ he was recommending.
Even with loose parts, adjustments can be made to minimize the tire wear and or people can be advised as to what needs to be repaired first to make the front end more reliable.
It's not all Black or White!!
