Have 90k miles 5.3 4x4.
For about 1 second, while accelerating, I hear the weirdest noise. It's like a droning of sorts. Other than the sound, everything seems fine.
What could this be?
thanks.

If it's the new body style..... & it is with the 5.3 motor...
It could be the drive shaft splined slip yoke sticking...
The yoke must extend & compress on axle wind up & over bumps..
The GM 'slippery' grease put on the splines ($35) or buy
the ($150) nickel plated slip yoke that doesn't stick.....
Be ware: There are a ton of Chev Slip yoke part Nos..
For ride quality improvement... Every Spring is a slip yoke
cleaning & greasing..... on my 00 5.3 Z-71 Ext. Cab LT.....
