Give a worn rear suspension pivot a fresh start with the Dorman suspension trailing arm bushing, part number 523-033. It is a direct-fit replacement for the 1998-2003 Toyota Sienna and is cataloged for both the rear left and rear right positions. See the "Vehicles it fits" section for engine details.
A trailing arm bushing sits at the pivot where the trailing arm mounts. It lets the arm move through its travel while absorbing road shock and vibration, and it helps keep the rear wheels located. Dorman builds this part to replace the original equipment:
- Direct replacement: designed to fit and perform like the original equipment on the listed applications.
- Reliable fit: precision-engineered to match the design and dimensions of the original components.
- Durable, weather-resistant construction: made to strict standards using sturdy, safe materials.
- Rigorously tested: checked through thorough quality-control measures.
A trailing arm bushing may need replacing if you hear clunking or knocking from the rear over bumps, if the vehicle feels loose or wanders, if the rear tires wear unevenly, or if the bushing looks cracked, torn or separated. The Dorman trailing arm bushing is cataloged for both rear sides, so we recommend replacing the left and right bushings together for balanced suspension behavior. Consult the vehicle service information for the installation steps, fastener torque, and whether the original fasteners may be reused.
