Detailed Description

Delphi TC4726 is engineered as a front right lower suspension control arm assembly for Subaru Crosstrek and Subaru Forester models from 2019 through 2024. Delphi applies OE-focused dimensional and material analysis to help maintain proper fitment between the replacement part and the original suspension layout. The assembly uses stamped steel construction, black painted finish, rubber bushings, and a chloroprene rubber dust boot for a service-ready replacement. The ball joint is pre-greased, uses a threaded stud, and mounts with a press-in design. Delphi TC4726 also cross-references MOOG Chassis Products RK623768 for the same application.

What This Part Helps Address

• Front-end looseness or wandering from worn control arm components
• Clunking or knocking noises from a deteriorated ball joint or bushings
• Uneven tire wear caused by suspension wear at the lower control arm
• Steering instability in the front right lower suspension corner
• Service replacement after corrosion, fatigue, or bushing failure

Installation Notes and Tips

Install TC4726 in the front right lower position only on confirmed Subaru Crosstrek and Subaru Forester applications. Verify mounting hole alignment, bore dimensions, and thread direction before installation. Because the ball joint is press-in and the assembly includes a threaded stud, proper suspension support and torque procedures are important during service. A professional alignment is recommended after replacement to restore suspension geometry.

Quality Assurance

Delphi subjects steering and suspension components to extreme temperature and salt-spray testing and uses dimensional and material analysis to support OE-level fit and performance expectations. Part number TC4726 reflects Delphi’s OE-focused aftermarket engineering for Subaru Crosstrek and Subaru Forester front right lower suspension service.
