Common Problems This Part Can Help Solve

• Clicking or snapping noises during turns
• Grease on the chassis or suspension from a ruptured CV boot
• Vibration or thumping during acceleration
• Wobble or instability while cornering
• Grinding noise from the front end is not addressed by this rear axle; rear driveline noise and joint wear are the primary service concerns for this application

Installation Notes and Tips

• Fits 2008-2014 Subaru Tribeca, rear left and rear right.
• Fits 2006-2007 Subaru B9 Tribeca, rear left and rear right.
• Do not let the CV axle hang unsupported during service; this can damage the inner joint.
• Use a torque wrench on the retaining nut and tighten to manufacturer specifications.
• Do not reuse the prevailing-torque lock nut; install the supplied new nut.
• Replace transaxle seals when servicing CV axle assemblies to help prevent leaks.
• If the ABS light is on after replacement, inspect the sensor ring, sensor, and wiring for damage.
