fwiw, i knocked my front alignment with a whack .. got a re-alignment. when i would do the early morning k-turn it would make a horrible sound and it felt like my front wheels were skipping on the tight turn. i swore up and down it was a bad alignment and it was coming from the front--dozens of experiences. my Father got in first time, heard/felt it and immediately looked behind him. said it was coming from the rear. said the differential needs to 'warm up' -- its been sitting all nite. idk what all that means .. but now i just drive around the block (rounding off the turn, not sharply) instead of K-turning so i don't have to experience it and it's 'warm' enough within 1/8 of a mile
