Detailed Description

This Dorman control arm assembly is engineered for OE-style replacement on the front right lower suspension. The boxed steel construction provides a rigid mounting structure, while the installed ball joint and included bushings help maintain proper suspension geometry and steering feel. Dorman 528-170 is a practical choice for Toyota 4Runner and Lexus GX460 owners addressing wear in the lower control arm assembly.

The part number 528-170 is listed for 2010-2024 Toyota 4Runner models with KDSS and 2010-2023 Lexus GX460 models in the front right lower position. This part cross-references Toyota 4806860050 and Monroe Shocks & Struts RK622834 for the same application.

What It Helps Fix

• Clunking or looseness from a worn lower control arm assembly
• Uneven steering response caused by suspension wear
• Directional instability during braking or highway driving
• Excess play from a worn ball joint or deteriorated bushings
• Front suspension noise from damaged mounting points

Installation Notes

Install on the front right lower position only. Verify KDSS-equipped fitment on Toyota 4Runner applications before ordering. Because the ball joint is installed and the assembly is pre-greased, installation can be more straightforward than rebuilding the arm separately. Always confirm alignment after replacement to restore proper suspension geometry.

Quality Assurance

Dorman uses an industry-leading evaluation process to validate fit, function, and durability for this suspension control arm and ball joint assembly. The goal is consistent ride quality, stable handling, and predictable dynamics in the specified vehicle applications.
