Product Details

Delphi applies OE-focused dimensional and material analysis to its aftermarket steering and suspension portfolio, helping maintain proper part-to-vehicle match. This lateral arm is engineered for the rear left lower forward position and uses rubber bushings to support suspension articulation while maintaining a factory-style replacement format. The TC8172 is cross-referenced to MOOG Chassis Products RK643392 for the same application.

Use Delphi TC8172 when servicing the rear suspension on a Nissan Pathfinder, INFINITI QX60, or INFINITI JX35. The steel arm and standard replacement design make it a straightforward option for restoring the specified rear left lower forward suspension location.

What This Part Helps Address

• Clunking or knocking from the rear suspension
• Excessive play in the rear left lower forward arm
• Uneven rear tire wear related to suspension geometry
• Loose or unstable rear-end handling
• Worn rubber bushings in the rear suspension linkage

Installation Notes

Install TC8172 only in the rear left lower forward position listed in the fitment data. Verify the 12.5 mm mounting hole diameter and compare the original arm before installation. Because mounting hardware is not included, reuse or replace fasteners as required by the vehicle service procedure. A professional alignment is recommended after suspension component replacement.

Quality Assurance

Delphi subjects its OE-based suspension and steering components to extreme temperature and salt-spray testing, along with dimensional and material checks, to support consistent fit and durability in aftermarket service.
