Dorman Rear Upper Control Arm with Pre-Installed Ball Joint — Passenger Side, OE-Style Fit

Dorman 527-192 is a rear passenger-side upper suspension control arm with a pre-installed ball joint, engineered as a direct replacement for select Infiniti and Nissan SUVs. This ready-to-install assembly replaces the original upper control arm and ball joint on compatible Infiniti QX56/QX80 and Nissan Armada/Pathfinder Armada model years. Built and tested to meet OE-style fitment and durability standards, the unit arrives with bushings and a ball joint already mounted so you can reduce labor time compared with replacing components separately. Before ordering, verify fitment using your vehicle make, model and trim in the garage tool to ensure proper compatibility.

What improvements does this assembly provide for rear suspension performance?

Replacing a worn control arm and ball joint restores factory suspension geometry, which helps return predictable handling and ride stability. Dorman’s testing focuses on strength and fatigue life so the part sustains expected loads during normal driving. Reinstalling a matched assembly reduces the risk of premature wear that can arise from mismatched components.

• Pre-assembled ball joint and bushings for consistent alignment
• Engineered to meet OE-style fit and function for affected models
• Coatings applied to resist rust and extend service life

How does installation time compare to rebuilding individual components?

Because the control arm arrives fully assembled with the ball joint and bushings installed, it cuts out the need to press-fit or press out components, which shortens shop labor. This makes it a convenient option for DIY mechanics and professional technicians who want a faster turnaround. Typical install time is reduced versus sourcing and installing separate parts.

• Comes with ball joint and bushings pre-installed to save pressing work
• Bolts onto the vehicle using existing mounting points—no custom modification
• Simplifies alignment checks after replacement versus component-by-component repairs

Which vehicles and years are compatible with this part?

This specific Dorman assembly fits a range of full-size Infiniti and Nissan SUVs across multiple production years. Always confirm the exact application by entering your vehicle’s year, make, model and trim into the fitment tool before purchase to avoid returns. Compatible groupings are listed below for quick reference.

• Infiniti QX56: 2004–2013
• Infiniti QX80: 2014–2024
• Nissan Armada: 2005–2015, 2017–2024
• Nissan Pathfinder Armada: 2004

What durability features help the assembly resist corrosion and wear?

The control arm is finished with protective coatings to reduce surface rust and extend usable life in road-exposed conditions. Material and coating choices were validated in Dorman’s evaluation process to withstand typical environmental stresses. Using a complete assembly also reduces the chance of moisture intrusion at joints compared with field-pressed repairs.

• Additional corrosion-resistant coatings on exposed surfaces
• Pre-installed bushings and sealed ball joint to limit contamination
• Manufacturing controls designed to maintain part-to-part consistency

This assembly is suited for owners and technicians who need a dependable, time-saving replacement for a worn rear passenger upper control arm and ball joint on select Infiniti and Nissan SUVs. If you want a direct-fit part that minimizes installation labor while restoring suspension geometry and stability, this pre-assembled Dorman unit is a practical option. Remember to use the vehicle fitment tool to confirm compatibility with your specific trim and year before ordering.
