Whining drivetrain

Back again guys.I just did my 318 over,rear end has a set of Richmond Gears,355 with sure grip,and a 4 speed.I put the car back together and now i have a vibration and a whine in the rearend when you let off the gas,no very little noise under load.The axles also have green bearings on moser axles.I put the back up on jack stands and no noise at 20 mpr.Let it idle in 2nd gear and there is a clunking noise every 4 or 5 seconds apart.Any help would be great.
