So what goes wrong with AF-S sonic motors?
Right over the last couple of days the motor for the Nikkor AF-S 80-200mm F2.8D arrived, it certainly feels smoother than the existing soon as my order for the motor was complete, the seller listed another...I'm thinking he has a few of these motors, they don't seem to too difficult to find.

The Nikkor AF-S 28-70mm F2.8D arrived yesterday, it's certainly a monster, in magnesium, weighing in at 1.012 kgs. The good news is the AF motor is still working, it squeaked lightly for couple of movements, and then it "shuffles along"........which is the noise they should make, then it stops at 3 meters.................. turning the focus ring I can feel something catching.

So today I start the big repair push......firstly with the 28-70!
