    Carrier Bearing

    Inspect/Replace

    • Sometimes, long driveshafts are made up of two pieces and have a center support bearing that is surrounded by rubber.
    A center support bearing.
    • If the bearing fails and seizes up, the rubber will be torn away from the bearing. The seized bearing can tear away the rubber mount that supports the outside of it allowing the bearing to rotate with the driveshaft. This allows the driveshaft to wobble up and down causing a vibration.
    • The rubber can also deteriorate due to age or contamination with oil. The driveshaft will operate at the wrong angle and vibration or noise will result. The vibration occurs most often during hard acceleration.
    • A worn center support bearing can cause a whining sound that varies with vehicle speed. The noise is constant in pitch, rather than changing or intermittent like U-joint noise.
