04 comp g started to notice a whine noise only on deceleration, goes away during acceleration. does not make the noise at idle, park or neutral, only on deceleration. was told by a friend it could be the thrust bearing in the final drive which would be nice because then i would not have to have the transmission removed just the differential cover. anybody had this problem before? i know its not the hub bearings due to the noise does not change while swerving back and forth and not a pulley. it does it in any gear while slowing down. Thanks
 


its clean, just had it completly overhauled about 5000 miles ago with complete valve body and all solenoids and torque converter.
 
Just had my trans. looked at and the final drive bearing went out and chewed up the planetary gears, now 200 bucks for a new final drive assembly. Good thing im friends with a GM trans. tech.
