Built For OE-Style Suspension Service

Dorman 520-447 is engineered as a replacement suspension control arm and ball joint assembly for the front left lower suspension on the Lexus LX570 and Toyota Land Cruiser. The steel stamped arm, rubber bushings, and installed ball joint are specified for light-duty suspension service, while the pre-greased construction helps simplify service preparation. This part cross-references Delphi TC3567 for the same application.

Common Problems This Part Addresses

• Front-end looseness or wandering caused by worn control arm bushings
• Clunking or knocking from a worn lower ball joint
• Uneven steering feel from suspension wear at the front left lower corner
• Directional instability during braking or highway driving
• Excess play in the lower suspension assembly

Installation Notes

Verify vehicle application by year, make, model, and front left lower position before installation. The ball joint uses a threaded stud and press-in mounting style, so proper suspension service procedures and alignment equipment are recommended after replacement. Inspect adjacent suspension components, fasteners, and mounting points for wear before reassembly.

Quality Assurance

Dorman uses an industry-focused evaluation process for this control arm and ball joint assembly to support smooth ride quality, directional stability, and predictable suspension dynamics. Part number 520-447 is built to match the OE-style function required for Lexus LX570 and Toyota Land Cruiser front suspension service.
