Hey Michelle, it has come to my attention that the 3.6L Rendezvous is an All Wheel Drive vehicle. So if you are sure that you have a 3.6L engine, then the rear fluid could be your issue. It uses a specific lube and has two oil pumps in it along with the gears. When the front end spins a bit the rear pumps rotate at different speeds and clamp the clutches on to power the rear axle. Whine can be from the pumps or internal pinion bearing or even the joint at the front of the torque tube. The unit bolts to the body with minimal isolation and noises become much louder. Lube is VersaTrak Fluid GM # 12378514
I will look into how to check the fluid if rotating the tires does not work.
