ADVANCED SERVICE INFORMATION
Subject:
Click/Popping Type Noise Coming from Front of Vehicle While Turning Steering Wheel at Low Speeds (Temporary Fix - Retorque Right Steering Gear Through Bolt, Permanent Fix - Under Development)
Models:
2004 Pontiac Grand Prix
Condition
Some customers may comment on a click or popping type noise coming from the front of the vehicle. This condition is most apparent when the vehicle is stopped or moving slowly, while turning the steering wheel 45 to 90 degrees in either direction.
To diagnose this noise, place the vehicle on a hoist after the vehicle has reached normal operating temperature. Using chassis ears or a stethoscope, listen to the right steering gear mount through bolt while turning the steering wheel back and forth 90 degrees. The noise should be louder at the through bolt.
Cause
Excess clearance between the frame (cradle) and the steel sleeve located inside the rubber bushing where the steering gear mounts may cause this condition.
Correction
To temporarily correct this condition, retighten the steering gear through bolt and nut to the correct torque of 48 N.m (35 lb ft). This will correct the condition for a period of time, but the noise will probably return. Engineering is currently developing a permanent fix. Once the fix is available, this bulletin will be reissued.
DO NOT replace the steering gear or the engine frame (cradle) for this condition, as the noise will reoccur. This noise condition will not cause any damage and, because the steering through bolt and nut assembly has a torque prevailing nut, it will not come loose.
Dealer Action
^ Record the customer information on a permanent record so you may call the customer when a permanent repair becomes available.
^ Please reassure the customer that this noise condition will not cause any damage and is only a nuisance.
^ Advise the customer that a repair is in test and validation and is due out soon. At the time the bulletin becomes available, it will be the dealer's responsibility to contact the customer.
