Detailed Description

Delphi TC3923 is engineered as a suspension control arm for the rear lower rearward location on 2005-2006 Nissan X-Trail models. Delphi applies OE-level dimensional and material analysis to help maintain proper alignment, suspension movement, and consistent fitment in the replacement process. The steel arm, black cataphoresis finish, and included bushings support durable service in demanding underbody conditions. This part cross-references Nissan 55121-8H510 for the same application.

What This Part Helps Address

• Excessive rear suspension play or looseness
• Clunking or knocking from the rear lower suspension area
• Uneven tire wear related to worn control arm bushings

Installation Notes and Tips

Fits 2005-2006 Nissan X-Trail, rear lower rearward. Verify the mounting points, arm orientation, and bushing condition before installation. Because mounting hardware is not included, reuse or replace fasteners as needed during service. A professional alignment is recommended after suspension component replacement to confirm correct geometry and tire wear characteristics.

Quality Assurance

Delphi subjects its steering and suspension components to extreme temperature and salt-spray testing, along with dimensional and material checks, to support OE-style performance and fit consistency. Delphi TC3923 is built to the same application-focused standards used across the brand’s aftermarket steering portfolio.
