Detailed Description

Delphi TC4792 is engineered as a direct suspension replacement for the front left lower corner. The arm uses stamped steel construction and a painted finish, while the included ball joint is pre-greased and press-in style for service on the specified Nissan platforms. Delphi validates parts through dimensional and material analysis, along with temperature and salt-spray exposure testing, to support OE-level fit consistency and corrosion resistance expectations.

This part cross-references MOOG Chassis Products RK621157 for the same application. It is a strong match for drivers servicing a Nissan LEAF or Nissan Sentra front suspension where the original control arm, bushings, or ball joint show wear. TC4792 is also listed against Delphi OE Solutions 522-913 and other aftermarket references for the same position.

Common Problems This Part Can Address

• Clunking or knocking from the front left lower suspension
• Excessive play from worn ball joint or bushings
• Uneven tire wear caused by suspension looseness
• Steering wander or reduced front-end stability
• Cracked, torn, or deteriorated control arm bushings

Installation Notes and Tips

Install TC4792 only on the confirmed front left lower position. Because the ball joint is press-in and the assembly is non-adjustable, proper suspension inspection and alignment checks should follow installation. Verify mounting hole size, bushing fit, and stud engagement before final torque. Mounting hardware, castle nut, cotter pin, grease fitting, and locking nut are not included.

Quality Assurance

Delphi applies OE-focused engineering and testing to this control arm assembly, including exposure to extreme temperatures and extended salt-spray testing. The result is a replacement part built around OE-style compatibility for the specified Nissan LEAF and Nissan Sentra applications.
