Installation Notes and Tips

Verify vehicle year, make, model, and front upper position before installation. Inspect the surrounding control arm, fasteners, and mounting surfaces for wear or damage before replacing the joint. Because this part uses a threaded, bolt-in design, proper torque and alignment procedures should be followed after installation. Confirm the tapered stud and castle nut engagement during assembly, and complete a front-end alignment if suspension components have been replaced.
