Common Problems This Part Addresses

Installation Notes and Tips

Verify the rear left rearward upper position before installation and confirm vehicle application by year, make, and model. Because the ball joint is press-in and the stud is threaded, proper suspension tools and torque procedures are important for correct installation. Inspect adjacent rear suspension components and alignment settings during replacement on Honda Accord, Acura TL, and Honda Crosstour platforms.
