I'm taking mine in tomorrow morning for this and will reference the TSB he mentioned. I hope this fixes my issue. Also getting some intermittent vibration around 75mph but I'm more concerned with the popping noises at this point.
I just picked up a 21 XLT yesterday and didn't notice this issue during the test drive. But it clunks anytime I turn with an incline / decline.
I love the truck but this will be my 3rd f150 with an issue within the first week of purchase.
Had an 11 lariat that had a grinding / scraping...
