Dorman 524-777 Rear Lower Forward Lateral Arm

Dorman 524-777 is a lateral arm and ball joint assembly for the rear lower forward position on select Subaru, Toyota, and Scion vehicles.

Key Features

  • Direct replacement lateral arm and ball joint assembly for rear lower forward suspension locations
  • Steel tubular control arm construction for OE-style fit and function
  • Ball joint included and installed
  • Pressed attachment type with threaded ball joint stud
  • Rubber bushings included for suspension isolation
  • Pre-greased design; greaseable: no
  • Regular grade replacement part from Dorman

What It Helps Address

  • Rear suspension looseness from worn lateral arm bushings
  • Clunking or knocking from a worn ball joint assembly
  • Uneven rear wheel tracking caused by suspension wear
  • Excessive rear-end play during braking, cornering, or acceleration
  • Restoration of OE-style rear lower forward suspension geometry

Installation Notes

Confirm the rear lower forward position and standard design application before ordering. This part cross-references MOOG Chassis Products RK100124 and Delphi TC5148 for the same application. Because the ball joint is already installed and the assembly is pre-greased, installation focuses on replacing the worn suspension arm with the correct OE-style component. Always verify fitment by year, make, model, and suspension position before service.

Quality Assurance

Dorman states that this lateral arm and ball joint assembly is precision-engineered and rigorously tested to provide reliable replacement performance on the specified vehicles. The part is built to match original equipment application requirements for the listed Subaru BRZ, Toyota GR86, Subaru Legacy, Subaru Outback, Subaru Forester, Subaru Crosstrek, Scion FR-S, Subaru Impreza, Subaru XV, Subaru XV Crosstrek, Subaru WRX, and Subaru WRX STI fitments.
