Detailed Description

This Dorman lateral arm, part number 522-378, is precision-engineered and tested to replace the original equipment link on specific vehicles. It is compatible with 2005-2010 Kia Sportage rear left lower forward and rear right lower forward positions, as well as 2005-2009 Hyundai Tucson rear left forward and rear right forward positions. The adjustable layout helps restore rear suspension geometry when the original arm is worn, bent, or no longer holding alignment. This part cross-references Delphi TC5872 for the same application.

What It Helps Fix

• Rear suspension looseness or clunking from worn link bushings
• Uneven tire wear caused by rear alignment issues
• Vehicle pulling or unstable rear tracking
• Corrosion or bending in the original lateral arm
• Excessive play in the rear suspension linkage

Installation Notes and Tips

Verify the rear left or rear right forward position before ordering, since fitment varies by vehicle and side. Because this arm is adjustable, a professional wheel alignment should be performed after installation. Inspect adjacent suspension components and replace any worn hardware or bushings as needed during service.

Quality Assurance

Dorman designs this replacement lateral arm to match the original equipment function on the listed Kia Sportage and Hyundai Tucson applications. The part is rigorously tested for fit and performance consistency across the confirmed vehicle range.
