Check your Power Steering fluid.
If your car has Versatrak all wheel drive, it probably the transfer case and rear differential. Changing the fluid will correct the problem. Make sure you use General Motors Versatrak Fluid only, nothing else is approved for these units!! It's expensive but it will correct the problem. You will need 4 bottles of fluid (2 liters). The transfer case is directly behind the transmission, simply drain and refill it and the rear diff after driving a few miles to warm them up. Take the car to a parking lot and make four or five figure 8's to get the new fluid into the clutch packs. The moaning should be better, but it may take about 500 miles of driving to completely eliminate it.
If that doesnt do the trick then its probably the belt. Especially during winter they get dried out or tighten up and crack so replacing it should stop the noise. Be easy on turns you dont wanna bust a cv (constant velocity) joint and it strains the belt the harder you turn.
Possible vacuum leak
your cv boot has torn and needs replacement
tie rod
A bad bearing can cause can the front end of car to make a squeaking noise when turning steering wheel either direction. It can also be caused by bad suspension.
The noise sounds like a "Growl" or a "roaring" noise. Generally you can also feel a slight vibration in the car as you drive.
no suv's do not make more noise than a car
Could be many things, ball joints usually make clunking noises (usually one when turning and one when turning the wheel from turning), cv joints usually make a clicking noise and vibrate under load. Have it checked out, les schwab will do it for free (check it).
If you lowered the car or had suspension/strut work done you can be rubbing The body in the boot?
The front wheel bearing is bad. The sound will be more pronounced when turning one way but not the other. The bad bearing is on the side of the car opposite the turning since more weight is on that side of the car when turning.
it could be a wheel bearing that is bad or it could also be busted belts inside a tire
It is probably the cover for your catalytic converter.
If it is a thumping and a front wheel drive car, it is probably one of the axles.
