Product Details

Delphi TC8398 is a rear left upper suspension control arm engineered for Land Rover Range Rover applications from 2007 through 2012. Delphi applies OE-level dimensional and material analysis to help ensure proper alignment of the arm, bushings, and mounting points. The part is tested for demanding temperature extremes and salt-spray exposure to support durability in harsh road conditions. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Repair Applications

• Rear suspension clunking or looseness from worn control arm bushings
• Uneven rear tire wear caused by suspension geometry issues
• Rear-end instability or wandering on a Range Rover
• Excessive play in the rear left upper suspension link
• Alignment problems after suspension wear or component replacement

Installation Notes

Verify the rear left upper position before installation and compare the original arm length and mounting points to the replacement part. Because mounting hardware is not included, reuse serviceable fasteners or source new hardware as needed. A professional alignment is recommended after replacement to confirm rear suspension settings on the Land Rover Range Rover.

Quality Assurance

Delphi uses OE-based engineering, dimensional checks, and material analysis to support fitment accuracy and durability. The part is also evaluated under extreme temperature and corrosion testing to reflect real-world suspension demands.
