I guess youre running lock-rites front and rear? I think the popping was your front axles unless they are spicers. Mine do that too I want to swap them out.
hi - yeah… they are fine. just noisy. i’ve had them in there for 3 yrs. i’ve taken them out and inpected them every year.. nothing wrong. they keep climbing. 🤗. i’ve heard them that loud on a couple of XJ’s too.
