08 4X4 LE.

When letting off the gas from 50ish mph and down the truck is making a growling like sound. Changed the diff oil tonight with no avail.
I did notice when slowing down rapidly that the pitch of the noise will change when the tranny downshifts. Noise dissipates when in neutral.
Any ideas?

It's the rear axle. You probably need new pinion and/or carrier bearings.
