2006 TRD Sport. Intermittant Resonate Drone ?

Just purchased truck with 174K, did't hear when I test drove it, now when it shifts between almost any gear or condition there a low level resontate growl intermittant. Even backing up slowly you'll hear it. Almost as if the the RPM's are to low for the shift Found the aluminum heat shild that was loose and secured it no change. Only heat it when it's going through the gears never at highway cruising speed. Any info greatly appreciated. Also brand new brakes on truck from what I've read the spongy feel is normal

Thanks,
Mark

Early universal joint wear can sound or more accurate feel like that. Try turning your drive shaft by hand. If it has any "play" you found your relatively inexpensive repair.

Good luck
