Subject: | "Hoot" Noise During Light Throttle Deceleration with Engine Speeds Between 3000 and 4000 RPM (Install Damper to Right-Hand Drive Axle) |
Models: | 1995 Saturn SC1 Coupes, Sl and SL1 Sedans, SW1 and SW2 Wagons with manual transaxle (MP2/MP3), ABS brakes (JM4) and steel wheels (PF0/PG1); built before including VIN SZ136841 |
A noise similar to "Hoot" is heard from inside some vehicles during very light throttle deceleration with engine speeds between 3000 and 4000 rpm. Because of the strict drivetrain torque conditions required for this noise to occur, it usually is noticeable only on vehicles equipped with manual transaxles.
he noise is caused by vibration that occurs under certain driving conditions, causing the drive axle to resonate.
Install a drive axle damper kit, following the procedures in this bulletin.
Important: Saturn vehicles described under "Models Affected," built after VIN SZ136841 have the drive axle damper installed at the plant.
Important: Drive axle shaft must be clean and free of grease to ensure the friction fit drive axle damper is secure tot he drive axle shaft after installation.
Notice: When installing the drive axle damper, make sure that the pipe used for installation presses on the inner drive axle damper ring. Pressing on the outer drive axle damper ring will damage the drive axle damper.
Important: If more than light-to-moderate tapping is required to move the drive axle damper, drive axle shaft splines or grooves are improperly taped or not enough liquid detergent has been applied.
Install outer CV joint drive axle. (Refer to "Drive Axle Assembly" in the "Drive Axle" section of the "1995 Chassis Service Manual.")
