My 2001 Aurora makes moaning noise at slow speeds when turning. Was told that this problem is common, but do not know what to do about it. Any suggestions?

There is a TSB on that subject. The repair depends on what engine is in your car...

Moan/Squawk Noise During Low Speed Turning Maneuvers (Replace Power Steering Gear or Pressure Hose AssemblyP #02-02-32-002 - (Jan 14, 2002)

2001-2002 Oldsmobile Aurora

with 3.5L V6 or 4.0L V8 Engine (VINs H, 6 -- RPOs LX 5, L47)

Built Prior to the Following VIN Breakpoints:

Engine VIN Breakpoint

3.5L 24131699

4.0L 24100112


Condition
Some owners may comment on an audible moan/squawk type noise that is heard during low speed turning maneuvers.

Cause
This condition may be caused by instability of the power steering gear valve. This may result in a pressure disturbance that creates an audible noise that is transferred through the vehicle structure.

Correction
Based on the engine type indicated below, replace either the power steering gear or the power steering pressure hose with the components indicated.

4.0L V8 Engine (RPO L47) Built Prior to VIN Breakpoint 24100112
Install a new power steering pressure hose, P/N 25737839, and secure the clip of the new hose to the frame with new screw, P/N 11515764, using the hole in the frame where the existing clip had been installed. The clip is to be positioned in a fore-aft direction with the hoop of the clip pointing forward and the attaching screw tightened to 7 N·m (60 lb in). To ensure the proper installation, refer to Power Steering Pressure Hose Replacement (L47) in the Power Steering System sub-section of the Service Manual (SI2000 Document ID #628527).

3.5L V6 Engine (RPO LX5) Built Prior to VIN Breakpoint 24131699
Install new power steering gear, P/N 26098941. To ensure the proper installation, refer to Power Steering Gear Replacement in the Power Steering System sub-section of the Service Manual (SI2000 Document ID #620339).

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
