Detailed Description

Delphi applies OE engineering standards to its aftermarket steering and suspension portfolio, and the TC7040 lateral arm reflects that approach with cast construction and rubber bushings for rear suspension service. It is engineered for the rear right upper position on 2000-2009 Subaru Legacy and 2008-2009 Subaru Outback models. This part cross-references Dorman OE Solutions 524-190 for the same application.

Delphi validates parts through extreme temperature exposure and salt-spray testing, along with dimensional and material analysis to support OE-style fit and function. For buyers searching for a Subaru Legacy rear right upper lateral arm or a Subaru Outback rear suspension arm replacement, TC7040 provides a focused match for the listed vehicles and position.

Common Problems This Part Can Address

• Rear suspension looseness or wandering caused by worn arm bushings
• Clunking or knocking from the rear suspension area
• Uneven rear wheel alignment after bushing or arm wear
• Excessive play in the rear right upper suspension link
• Restoring rear suspension geometry on aging Subaru Legacy and Subaru Outback vehicles

Installation Notes and Tips

Verify the rear right upper position before installation and compare the original arm length and bushing layout to the replacement part. Because mounting hardware is not included, reuse or source the correct fasteners as needed. A professional alignment is recommended after suspension arm replacement to confirm rear geometry and tire wear settings.

Quality Assurance

Delphi backs this suspension component with OE-focused testing and material validation, including temperature cycling, salt-spray exposure, and dimensional checks to help ensure consistent fitment and durability for the listed Subaru applications.
