Hey everybody,
About 2 years ago I purchase a certified pre-owned 2015 Tahoe with 56K miles. I have had to take it into the show 6 times now. 2 times for Front Diff bearings and ring gear & pinion replacements. It was making noise in auto and 4H. About a year ago I took it in because of this knocking noise (video linked below). The noise is not related to speed or acceleration and I cant make it happen on command. The dealership has had my car for 3 days and didn't find anything. Anyone got any ideas? Quick notes: since taking it to the dealer I replaced both the front struts and now have 75K on it. The noise is still there randomly but doesn't seem to be effecting anything for now.
This is recorded from the front, driver side footwell. I was in 2W and I was driving straight on the highway at 70MPH. It was a flat highway (95). The noise has happened at lower speeds. It seems to happen randomly after sharp turning or heavy breaking.
