Interesting information. I have a similar problem and haven’t been able to find it. I swapped in both new leafs and did an 8.5 swap at the same time. Since then, when you goose the throttle from a stop I get a clunk somewhere behind me. This is especially prevalent if you are on an uphill incline. It will do it almost every time then.

I’ll check my exhaust at the frame rails too. I had been figuring it was the driveshaft hitting my x pipe. The exhaust was built to clearance with the old saggy springs. That said, I can’t find any actual evidence of this.
