what?! you gotta be kidding?!!!! the noise actually went away with that kind of tire pressure delta??? i can't see how altering the tire pressure would alter the suspension & drivetrain alignment. i could see how it affects the chassis attitude, but, not the drivetrain. in general, the car should NOT be driven with that kind of tire pressure difference. that can't be safe.
i guess this IS just the nature of the beast or there's too much compliance in the drivetrain supports that allow the driveshaft to deflect relative to the rear diff upon deceleration.
who knows. and i don't think the dealership techs have the know how to figure this one out...
does anyone have a contact email address for tech support for SOA?
