The No. 9 car of Chase Elliott was disqualified for having four loose lug nuts after the Ally 400 NASCAR Cup race in Nashville Sunday.
“It’s unfortunate. The lug nuts on the No. 9 were loose at the end of the race,” said his Crew Chief Chad Knaus.
“At the end of the race Chase had a vibration. There were quite a few tire issues through the course of the day so they were hopeful that it was just a cord or something in the tire that was creating the vibration so they chose to run the race out. It’s unfortunate that the lug nuts vibrated loose on the left rear and now we are sitting here with a disqualification for the 9 team.”
