Product Details

This suspension knuckle bushing is built to match the original equipment design for the listed application. The steel and rubber construction helps restore the connection point between suspension components while maintaining the intended bushing function. Dorman 540-146 is a practical OE-style replacement for a Hyundai Tucson rear lower suspension repair when the original bushing is worn, cracked, or no longer holding alignment as intended.

Common Problems It Can Help Solve

• Rear suspension looseness or excess movement
• Clunking or knocking from the rear lower suspension area
• Worn, cracked, or deteriorated bushing material
• Loss of suspension stability at the knuckle mounting point

Installation Notes and Tips

Verify the vehicle application before installation. This part is specific to the rear lower position on the listed Hyundai Tucson model years. Inspect the surrounding suspension components, mounting surfaces, and fasteners for wear or damage before pressing in the new bushing. Professional installation is recommended because suspension bushing service typically requires proper tools and careful alignment during assembly.
