Dorman 528-042 Suspension Control Arm and Ball Joint Assembly - Rear Right Upper

OE-Style Rear Right Upper Control Arm

Dorman 528-042 is a direct replacement suspension control arm and ball joint assembly for specific INFINITI and Nissan applications. It is built for the rear right upper position and uses a pre-greased, installed ball joint to support smooth ride quality, directional stability, and predictable suspension movement.

Compatible with 2014-2020 INFINITI QX60, 2013-2020 Nissan Pathfinder, and 2013 INFINITI JX35, this Dorman 528-042 assembly is a practical OE-style replacement for worn rear suspension components.

Key Features

• Direct replacement for the original equipment control arm and ball joint assembly
• Fits the rear right upper suspension position
• Pre-greased with the ball joint installed
• Steel casting/forged construction for strength and durability
• Includes bushings with rubber and steel materials
• Machined ball joint mounting with pinch-style stud design
• Black finish
• Regular grade, light suspension application

Detailed Description

Dorman 528-042 is engineered as a direct-fit suspension control arm and ball joint assembly for the rear right upper location. The steel casting/forged construction, installed ball joint, and included bushings provide a complete replacement solution for vehicles that need restored rear suspension geometry. This part cross-references Nissan 555013JA0A for the same application.

For INFINITI QX60, Nissan Pathfinder, and INFINITI JX35 applications, this assembly supports consistent suspension response by replacing a worn control arm and ball joint with an OE-style unit built to match the original layout. The pre-greased design and machined ball joint mounting help simplify service while maintaining proper fitment.

What It Helps Fix

• Rear suspension clunking or looseness from worn control arm components
• Uneven tire wear caused by suspension geometry issues
• Rear-end instability or wandering during driving
• Excessive play from a worn ball joint or bushings
• Noise from deteriorated upper rear suspension hardware

Installation Notes and Tips

Install this assembly in the rear right upper position only. Verify vehicle application by year, make, and model before service, and inspect adjacent suspension parts for wear during replacement. Because mounting hardware is not included, reuse or source the correct hardware as needed for the vehicle.

Quality Assurance

Dorman evaluates this suspension control arm and ball joint assembly through an industry-focused validation process to help maintain smooth ride characteristics, directional stability, and predictable suspension dynamics. Dorman 528-042 is built for specific OE replacement applications and is intended to match the original suspension layout on the listed vehicles.
