Detailed Product Overview

Dorman 527-121 is a suspension trailing arm engineered as an OE-style replacement for the rear lower position on the Nissan Quest. The arm uses a tubular steel body with a black coated finish, a bracket end, and a bushing end to match the original suspension layout. Its 333 mm length and 12.5 mm mounting hole diameter support proper fitment in the intended application. This part cross-references Nissan 55110CK000 for the same application.

Common Problems This Part Can Address

• Rear suspension clunking from worn or deteriorated bushings
• Uneven rear wheel tracking caused by a bent trailing arm
• Excessive play in the rear lower suspension link
• Corrosion-related failure of the original steel arm
• Unstable ride quality or inconsistent rear handling response

Installation Notes and Tips

Verify vehicle fitment by year, make, model, and rear lower position before installation. Mounting hardware is not included, so reuse or replace fasteners as needed during service. Because this is a bolt-on trailing arm with no adjustability, proper alignment and torque procedures should be followed after installation on the Nissan Quest.

Quality Assurance

Dorman designs this trailing arm as a direct replacement and subjects it to rigorous evaluation for secure performance and consistent ride control. The part is built to support safe suspension operation in the intended 2004-2009 Nissan Quest rear lower application.
