Update:
Had to drop my Talons skid/cat shield to get torque wrench on rear LCA nuts. Service manual stated 129 ft lbs for the bolt and nuts. All seemed to be torqued as I didn't notice any movement prior to reaching torque specs.
However, initial test drive did not have the popping noise, so...
2017 with 61K miles has developed a front in popping noise that I can't seem to locate.
Sounds like it is coming from driver's side. Only thing I could find loose was the driver's C/V axle at the diff. I replaced front sway bar bushings and had local 4x4 shop install the ECGS clam shell...
