You ordered part # Rancho rs62148 for 179? In person or online. 4 wheel Parts here in Las Vegas had to call Rancho to get one as its not in their computer yet. They charged me 325 strange. The rear was only 161, and the rear shock skids were only 161.
You must have gotten it, I just ordered the new plate for the front of my 2022 Rubi Gladiator. Crazy the rear and older front was $170 and the new front is $325.
I had the same noise. It was part of the tpms sensor inside the tire broke off. It rides up then falls down and hits the top of the rim inside the tire. Remove that tire and roll it, I bet you hear that noise.
