If its a groaning noise and its worse when cold it might be the power steering fluid is low, as the vehicle warms up the level rises and the pump stops sucking air, check the power steering fluid first
The bubbles are more or less normal. I would want to know for sure the noise is coming from the pump and not another pulley on the engine. When you turn the wheels you put load on the pump and the drive belt which loads the other pulleys too. How about taking a long piece of heater hose and using it to listen around the belt while a helper turns the steering wheel ?
generally means a power steering pump issue. Go to a car parts store website and find one for your car, then find the thing under the hood, mounted to the engine and being spun by the belt, which looks just like it. often there is a cap with a dipstick and you can check the steering fluid level. if the level is way down you may have a leaking hose or other component.
about 2000 there was a shift away from the old style fluid pumps to electronic systems so do not be stunned if there is no such thing as a power steering pump for your car. but if the noise gets louder by moving the steering wheel, you still need to look at whatever is boosting the steering wheel motion to steer the car.
you can hear your power steering pump working and if it's whining, it may be low on fluid.
Check the fluid level with the engine running and be very careful of moving or rotating parts.
Locate the pump and check the level (the cap will usually have a dipstick to measure the level attached to the cap and you read it the same way as your engine oil dipstick). DO NOT overfill the pump as it will just leak out and cause other issues.
If the level is very low, top it up then work the steering from side to side a few times then recheck the level. Careful, power steering fluid can get very hot!!
If the fluid in the pump looks dark or black, take the vehicle to your local mechanic and have the fluid replaced and the system flushed.
normally, the only part of your automatic transmission that will make a whining noise is the pump. it usually whines when iether the fluid is low or more commonly when the transmission oil filter is getting plugged up.
the power steering pump will also make a whining noise too.
turn the wheel all the way to the right and hold steady pressure against the stop. this puts maximum force on the power steering pump and, if the power steering pump is the one making the whine, it will change the sound of it. (usually louder).
if the trans pump is making the whine noise, it should sound different in neutral compared to drive. this test will really only work if it make the noise without the vehicle moving. if it wont do it at idle hold the rpms at 2000 or so.
if you decide the noise is coming from the transmission, and the transmission filter has not been replaced (assuming you installed a used transmission), replace the filter by removing the oil pan.
oh and also, if it is the power steering pump you should be able to make it make the whining noise while the vehicle is stationary. if it wont make noise unless its moving its not the power steering pump.
If you have a warranty from your dealer, you paid for it, or whether it came with it, it doesn't matter, you MAKE them honor it. Take it back there, and MAKE THEM FIX IT! This shouldn't be your problem if you have a warranty. If they aren't honoring it, threaten them with the BBB or court. They will shape up. I would say power steering pump.First check to make sure there is fluid in the reserve tank and at the proper level if not top it off and whine should stop.If level is correct then maybe try flushing with fresh fluid. 3.8L engine the power steering fluid was never toped/checked.. because it is a pain in the *** to get at (behind the hot as hell alternator), so it probably ran dry, top it up is probably all you have to do.. if the whining presists then you will have to try and bleed the air out by jacking it up, engine off, turn the wheel one side to the other about 25 times.. if that dont quiet it up then you will have to replace the power steering pump. Power steering pump / fluid level is not hard to check - it is located below the alternator on the passenger side of the engine bay. You need a light to see it. You can get your hand down from the top of the engine to loosen and remove the cap/dipstick.

Make sure you have enough fluid, and honestly, regardless of the fluid level, change it and put in new transmission fluid. If it's an automatic, change the transmission filter too. You can try adding some Lucas stabilizer as well. If that doesn't do it, you may be looking at a rebuild or replacement.
