2016 Yukon Danlie 4WD 6.2l- 70xxx miles-
Just developed a "bird chirp" type noise that matches RPM. Took it in thinking maybe a pulley or....
Turns out they came back and are telling me camshaft actuator---- repair cost $7k
Scouring the webs, and can't seem to find much in this specific repair on this one. Anyone have any insight other than I should just pull em down and take it?
