Pontiac Aztek AWD: Just got it back from shop and still making 'jet like'...

[Right Ting!]

...noise on acceleration.? Had Right Wheel Bearing hub replaced, wheel bearings, 4 pints of differential fluid added (not sure why???), and it makes this jet like 'take off' noise while accelerating at certain speeds.

It has Versatrak All Wheel Drive. What would cause this noise and why does it do it? Please help...

Not too sure I follow you on the whole jet like noise thing. could be as simple as your tires or alignment. I'm imagining a very loud roar of compressed fuel/air creating vast amounts of thrust.
