Here'* some GM inside info for you 2000 - 01 Bonneville owners out there.
Hot Tip #5:
Subject: Intermittent Squawk or Groan Noise from Steering System >>> 09/13/02
Vehicles Affected: 2000-01 Bonnevilles
Summary: Replace Steering Gear & High Pressure Hose Assembly.
This is a situation where the owner may comment that the steering system emits a load squawk noise at times when the steering is turned at low speeds. The likely cause for this issue is an internal steering gear resonance. To correct this condition, replace the components outlined in this hot tip. Note that these parts are for vehicles with specific options. Care must be taken to get the right parts for the application. This information only applies to cars with Magna-steer "E" that was installed in some models in the 2000 model year.
The steering gear for the 2001 Bonneville SSEi is now available and can be used to correct a squawk concern on a 2000 or a 2001 Pontiac SSEi. Use steering gear P/N 26099978. Steering gear will be substituted with an updated gear.
These parts went into production at the following VIN break points: H Body gear 1G2HZ541224100674

Steering Column Pop/Noise
Group Ref.: Steering/Suspension
Bulletin No.: 333210A
Date: December, 1993
STEERING COLUMN POPPING NOISE (REPLACE UPPER BEARING INNER RACE SEAT)
1992-93 PASSENGER CARS EXCEPT CHEVROLET CAVALIER. GEO AND PONTIAC LEMANS
1992-93 LIGHT DUTY TRUCKS EXCEPT GEO TRACKER
Vehicles affected have TILT steering columns (round style) with the exception of the "W" series (square style).
Some owners of vehicles with integral TILT steering columns may hear a pop noise when turning. The noise occurs specifically when the driver is
making normal steering turns in either direction and generally when the steering wheel is returning to center.
The upper bearing inner race seat under certain conditions may cause a pop noise. The part may have a burr on the inside skirt.
To verify that the upper bearing inner race seat is the cause of the pop noise in the steering column, use the following method:
1. Engage the park brake and start the engine.
2. Point the wheels of the vehicle straight ahead.
3. While listening for a pop noise, rotate the steering wheel in either direction to the wheel stop. Slowly return the wheel back to center. If the
noise is not heard, drive the vehicle at a slow speed listening for the noise to occur.
When the steering column is warm, the pop noise will be more audible.
4. If a pop noise is heard, replace the upper bearing inner race seat with P/N 7815184. Return the steering wheel back to center with the wheels
of the vehicle pointed straight ahead. Turn the ignition lock cylinder to "LOCK" position and then begin the repair. Refer to Section 3F5A/3F5B in the Service Manual to replace the upper bearing inner race seat.
