Installation Notes and Tips

When installing the Dorman 526-659 control arm, ensure the vehicle is securely lifted and supported. Since mounting hardware is not included, reuse original bolts or acquire appropriate replacements. The control arm features two mounting holes with a diameter of 17.61 mm, so verify compatibility with your vehicle’s mounting points.
