Introduction Some 2004 – 2006 model year Sequoia vehicles may display one of the following conditions from corrosion inside of the rear axle assembly caused by water intrusion. S An abnormal noise described as a “rumble,” “roar,” or “whir” that seems to be coming from the front of the vehicle that increases in sound level with increased vehicle speed between 20 – 60 mph (32 – 97 km/h) with the noise most noticeable between 30 – 40 mph (48 – 64 km/h). S Intermittent activation of ABS, VSC, and/or TRAC systems on dry flat pavement while driving. VSC/TRAC light flashes intermittently. A revised rear axle bearing has been developed to prevent water intrusion. Repair Procedure 1. Test drive the vehicle and confirm that the abnormal noise is occurring. 2. Using ChassisEARt, confirm that the source of abnormal noise is one or both of the rear axle bearings.

NOTE: If ChassisEARt is NOT available, raise the vehicle on a lift and use a mechanics stethoscope to confirm that the source of the noise is one or both of the rear axle bearings. 3. Place the vehicle on a lift and raise the vehicle. 4. Remove ABS speed sensor on the axle side with the identified bearing noise and examine the inside of the rear axle housing for corrosion. A. Disconnect the speed sensor connector. B. Remove the speed sensor. a. Remove the 6 resin clips holding the sensor wire harness. b. Remove the bolt and speed sensor from the axle carrier. Torque: 8.0 NSm (82 kgfScm, 71 in.Slbf) 5. If surface corrosion is visible, replace the bearing with the revised part. 6. Refer to the Technical Information System (TIS), 2004 – 2006 model year Sequoia Repair Manual: Suspension and Axle: Rear Axle Shaft: Removal and Suspension and Axle: Rear Axle Shaft: Disassembly to remove the rear axle bearing assembly.
