Yea i had those alignment nuts on the cross shaft on the upper a arms get loose on my Old B-body Impala/ Caprice stuff So many shops when shops messed with the alignment shims DID NOT tighten those nuts properly
Sometimes the fix is just looking closely and acting accordingly, I agree with the modern car dislike, I drive a 1966 Chevy 2 myself!👍 Thanks for the video Dan👏
