Mine “2500 hd” had a clunk after I got thuren suspension on. It was 100% the track bar not fully tq’d. I can imagine even if they didn’t tq the stock one right it would make the noise too. First place I’d check if it was me. And we’re talking tq not impact tight. That’s how they installed it and it was noisy. Went and rented a tq wrench and I did it properly. Noise gone.
