Detailed Description

Delphi TC5173 is engineered as a standard replacement suspension control arm for the front left lower position. Delphi applies OE-focused dimensional and material analysis to help maintain proper fit and suspension geometry, and the part is tested across extreme temperature and corrosion conditions to support long-term service in demanding environments. This part cross-references Beck/Arnley 102-6038 and MOOG Chassis Products RK620343 for the same application.

What It Helps Repair

• Front-end looseness or wandering on Mercury Villager and Nissan Quest models
• Excessive suspension play from worn control arm bushings
• Clunking or knocking from the front left lower suspension area
• Uneven tire wear caused by worn suspension geometry components
• Restoration of stable steering response after control arm wear

Installation Notes and Tips

Fits 1999-2002 Mercury Villager, front left lower. Fits 1999-2002 Nissan Quest, front left lower. Verify the front left lower position before installation and inspect related suspension components, including bushings and alignment settings, during service. Because mounting hardware is not included, confirm all required fasteners are on hand before beginning the repair.

Quality Assurance

Delphi uses OE-based engineering and validation methods for its aftermarket steering and suspension portfolio. The TC5173 is built with compatibility-focused dimensional and material analysis and is exposed to temperature and salt-spray testing to help verify durability in service.
