Detailed Description

Moog RK100354 is engineered as a premium rear left upper control arm for select Lexus and Toyota vehicles. It is a direct-fit suspension control arm for the rear left upper position on 2006-2019 Toyota RAV4, 2015-2017 Lexus NX200t, 2015-2021 Lexus NX300h, and 2018-2021 Lexus NX300. The forged steel body adds strength, while the included rubber bushings help isolate suspension movement and maintain consistent rear suspension geometry. The adjustable eccentric design supports camber correction within the specified range, making RK100354 a practical replacement when rear alignment needs to be restored. This part cross-references Dorman OE Solutions 524-005 for the same application.

Common Problems It Can Address

• Rear suspension looseness or excess play at the control arm
• Uneven rear tire wear caused by incorrect camber
• Alignment issues after suspension wear or component replacement
• Noisy or deteriorated rear control arm bushings
• Restoring rear left upper suspension geometry on Lexus NX300 and Toyota RAV4 models

Installation Notes and Tips

• Install at the rear left upper position only for the listed applications.
• Use the eccentric adjustment during alignment to set rear camber within the specified range.
• Because this is a non-greasable control arm, routine lubrication service is not required.
• Verify vehicle fitment by year, model, and rear suspension configuration before installation.
• Professional alignment is recommended after replacement to confirm final settings.
