Installation Notes and Tips

Verify rear fitment by year, make, and model before installation. This trailing arm uses a press-in attachment type and does not include mounting hardware, so inspect related fasteners and mounting points during service. Because the arm is not adjustable, proper installation and alignment checks are important after replacement. Confirm the rear suspension configuration on your vehicle before ordering Dorman 526-433.
