Detailed Description

This Dorman lateral arm, part number 524-786, is made for rear left lower rearward and rear right lower rearward positions on select Subaru vehicles. It is a regular-grade stamped suspension arm with steel construction and rubber bushings, built to match the original design used on 2008-2014 Subaru Impreza, 2009-2013 Subaru Forester, 2012-2014 Subaru WRX, 2013-2014 Subaru WRX STI, and 2013 Subaru XV and XV Crosstrek models built to 7/12. This part cross-references OE-style applications such as 20250AJ040 and 2607830 for the same application. If you are replacing a worn rear suspension lateral arm on a Subaru WRX or Subaru Forester, Dorman 524-786 provides the correct OE-style geometry for the listed positions.

Common Problems This Part Can Address

• Rear suspension looseness or clunking from worn arm bushings
• Uneven rear tire wear caused by suspension wear
• Rear alignment issues after arm or bushing deterioration
• Excessive rear-end movement over bumps or during cornering
• Corrosion or fatigue in the original lateral arm assembly

Installation Notes and Tips

Verify the rear left lower rearward or rear right lower rearward position before ordering. Confirm vehicle year, model, and build date for 2013 Impreza, XV, and XV Crosstrek applications, since coverage is listed to 7/12. Mounting hardware is not included, so inspect existing fasteners and replace any worn hardware as needed. After installation, a professional wheel alignment is recommended to restore rear suspension geometry.

Quality Assurance

Dorman manufactures this lateral arm as a tested replacement part for specific OE applications. The steel construction, included bushings, and OE-style stamped design support consistent fitment on the listed Subaru models, including Subaru WRX, Subaru WRX STI, and Subaru Forester applications.
