2012 GC, Pentastar 6 and Mall-Wheel-Drive. Just started clicking on acceleration, not consistently but easily 50% of the time. Frequency of clicking varies with vehicle speed. No rocks stuck in the treads,interior cargo is secured.
I got underneath yesterday and shook the front and rear drivelines. There’s a little less than 1/8-turn rotation, and a little front-back movement on front shaft. Didn’t get a look at the carrier bearing (bad angle, still in work clothes, other excuses). CV boots look fine. Connections to trans and differential feel solid.
What say ye? My suspicion is the carrier bearing, but I’ve never dealt with one before. Is there supposed to be a little slop in the driveline?
