KC 2013 Tahoe
TYF Newbie
2013 Tahoe, 5.3L, 127K miles.
Bought her used at ~46K miles.
I change the engine oil/filter every 4K miles, Trans fluid/filter every 2 years, transfer case and diff's every year.
Engine runs and idles smoothly, right at 500RPM in Drive per the dash tach.
When pulling away from a traffic light from idle, we'll periodically get a solid "clunk" that you can feel. (probably 1 out of every 4 times)
Feels like its coming from transfer case area but not certain.
Started doing this about a year after getting her, but never have been able to detect where its coming from, nor has it caused any problems.
It's very mild under a light throttle, but very pronounced if you hit the gas hard, say to pull out onto a major street.
Again, the odd thing is that it's periodic and doesn't do this every time.
FWIW, we had the Trans and Torque converter rebuilt 2 years ago at 110K miles after the converter failed. Made no difference at all.
Saw some posts about older models having a slip yoke binding issue, but 2013 was supposed to be well after those issues.
When I'm underneath to service it, there's no unusual play in the driveshafts either to the front or rear diff's.
It's hard to tell exactly, but does feel as if its coming from the transfer case area.
What really stumps me is the periodic nature. If it was wear, would think it would do this every time.
Also seems odd, as I believe the driveline is loaded-up when idling in gear. So even if there is drivelline slop, the preload from the trans being in gear while idling should keep any lash from being felt. Very odd.
