Installation Notes and Tips

Verify the rear left upper position before installation and confirm vehicle year, make, and model against the fitment list. Because the ball joint is press-in and the stud uses a pinch-style design, proper suspension service tools and torque procedures are important for correct installation. Inspect adjacent rear suspension components during replacement to avoid repeat repairs. X47CJ1393 is also a useful search term when ordering the correct Subaru rear left upper control arm assembly.
