Delphi TC2158 Suspension Control Arm and Ball Joint Assembly - Front Left Lower

Delphi Front Left Lower Control Arm Assembly

Delphi TC2158 is a front left lower suspension control arm and ball joint assembly built for OE-style replacement on select Volvo applications. It combines a stamped steel arm, pre-greased construction, rubber and steel bushings, and a threaded ball joint stud for direct-fit service on compatible vehicles.

Fits 2006-2015 Volvo S80, front left lower; Fits 2009-2010 Volvo V70, front left lower; Fits 2011, 2014-2015, and 2017-2018 Volvo V60, front left lower; Fits 2011, 2013-2014 Volvo S60, front left lower.

OE-Style Suspension Replacement

Delphi applies OE engineering and dimensional analysis to aftermarket steering and suspension parts, and TC2158 follows that approach for Volvo S60, Volvo S80, Volvo V70, and Volvo V60 front left lower applications. The arm is built from stamped steel with a threaded 14.0 mm ball joint stud and a 28.0 mm stud length, helping maintain the original suspension geometry and fitment profile. This part cross-references Beck/Arnley 102-7547 for the same application.

Common Issues This Part Addresses

• Front-end clunking or knocking from a worn lower control arm
• Excessive play from deteriorated ball joint or bushings
• Uneven tire wear caused by suspension looseness
• Steering wander or reduced directional stability
• Restoring proper front left lower suspension support on Volvo S60, S80, V70, and V60 models

Installation Notes and Tips

Verify chassis serial number notes before ordering, especially for 2011 and 2013-2015 Volvo S60 and 2015-2018 Volvo V60 applications. Confirm the front left lower position, inspect adjacent suspension components for wear, and perform a wheel alignment after installation. Because the assembly is pre-greased and not greaseable, no grease fitting service is required.

Quality Assurance

Delphi subjects its OE-based steering and suspension components to temperature extremes below -40 degrees C and above 120 degrees C, along with extended salt-spray exposure, to evaluate durability and corrosion resistance. TC2158 is a standard replacement part built to support OE-level fit and material compatibility for the listed Volvo applications.
