MOOG Front Left Control Arm & Ball Joint Assembly RK621477 — OE Fit, Corrosion-Resistant

MOOG RK621477 is a front left lower suspension control arm and integrated ball joint built to restore alignment and handling on compatible Toyota and Lexus vehicles.

This assembled control arm from MOOG replaces worn or damaged suspension components with a single, ready-to-install unit engineered for strength and corrosion resistance. It is purpose-made to match factory mounting points and suspension geometry for the 2005–2018 Toyota Avalon, 2007–2018 Lexus ES models, and multiple Toyota Camry model years, helping drivers recover predictable steering response and stable wheel alignment after wear or impact.

How does this MOOG assembly affect steering feel and wheel alignment?

Replacing a fatigued control arm and ball joint with this OE-style MOOG unit reduces play and restores the arm’s designed pivot points. That leads to crisper steering input, more consistent tire contact patch, and improved ability to hold alignment settings during normal driving.

• Factory-compatible mounting points for proper alignment geometry
• Integrated ball joint reduces joint looseness and steering wander
• Sturdy construction keeps caster and camber stable under load

What vehicles and model years does the RK621477 fit?

MOOG RK621477 fits a range of Toyota and Lexus sedans across multiple years. Confirm fitment by VIN or parts lookup before purchase to ensure correct side and front/lower application for your specific vehicle.

• 2005–2018 Toyota Avalon
• 2007–2011 Toyota Camry and 2012–2017 Toyota Camry variants listed
• 2007–2018 Lexus ES350 and 2013–2018 Lexus ES300h

What are the construction and corrosion-protection features?

MOOG builds this control arm from durable materials selected to withstand road loads and everyday stress. Surfaces are treated to resist rust and the overall assembly is reinforced at key stress points to extend service life compared with worn originals.

• Reinforced arm sections to handle suspension forces
• Corrosion-resistant finishes for longer on-vehicle life
• Pre-assembled ball joint for consistent torque and fit

Can I install this myself and what should I expect during replacement?

The MOOG RK621477 is supplied as a complete assembly to simplify installation and reduce alignment drift from partial replacements. Basic mechanical skills and standard tools are usually sufficient, but a professional alignment is recommended after installation to ensure proper tire wear and handling.

• Delivered pre-assembled to shorten bench time
• Typical install requires removal of wheel, control arm bolts, and ball joint fastener
• Follow-up wheel alignment recommended after replacement

Who this is for: This MOOG front left lower control arm and ball joint assembly is aimed at Toyota and Lexus owners, independent mechanics, and DIY enthusiasts who need a durable, OE-compatible replacement to restore safe steering and predictable handling. It’s especially relevant where worn suspension parts are causing uneven tire wear, steering looseness, or alignment problems and the vehicle matches the listed model years. For precise fitment, verify part compatibility with your VIN or vehicle specifications before ordering.
