Common Repair Uses

• Restoring smooth power transfer after CV joint wear
• Replacing a torn or leaking axle boot
• Correcting clicking or popping during turns
• Addressing vibration from a worn front axle shaft
• Repairing axle damage from road impact or corrosion

Installation Notes and Tips

Verify the vehicle’s VIN, production date, and axle position before ordering, especially on 2009 and 2014 Subaru applications with split fitment notes. Confirm the axle nut thread size, spline count, and overall compressed length against the original shaft before installation. Because ABS tone ring is not included, confirm the vehicle’s ABS configuration and original axle design before service. Use the included axle nut and follow Subaru torque and staking procedures during installation.
