Front Lower Control Arm w/Ball Joint Replacement - Fits Lexus & Toyota

In this review the focus is on a practical replacement part for older Lexus and Toyota models: the Front Lower Control Arm w/Ball Joint kit. The reviewer finds this two-piece kit best suited for owners needing a durable, like-for-like suspension repair without unrelated upgrades. The single biggest reason to buy is the kit's straightforward compatibility and solid construction, which replace worn lower control arms and ball joints for a range of Lexus ES and RX models and Toyota Avalon, Camry, Highlander and Solara vehicles with minimal fuss.

Key Features

• Broad compatibility: Covers multiple model years of Lexus ES300/ES330/ES350 and RX330/RX350/RX400H so buyers can match parts to several vehicles without guessing.
• Direct replacement part numbers: Replaces K620333 and K620334 for an exact fit where those numbers are referenced in service guides or parts lists.
• Durable construction: Built from high strength steel tubing and solid plate mounting brackets to restore suspension stiffness and resist deformation under load.
• Corrosion resistance: Anti-corrosion coating on the control arm extends service life in wet or salted-road conditions.
• Complete kit: Two front lower control arms with integrated ball joints and included mounting hardware make the job more straightforward for a DIY mechanic or technician.

Who It's For

This kit is aimed at owners of mid-2000s Lexus ES and RX models and various Toyota sedans and SUVs who need a like-for-like repair to the front lower suspension. It suits DIY mechanics comfortable with front suspension work and professional shops that prefer preassembled control arm and ball joint units to save labor and ensure consistent parts quality.

It is not aimed at buyers seeking performance tuning or upgraded suspension geometry; anyone after adjustable arms, cosmetic upgrades, or application outside the listed model years should look elsewhere to avoid fitment issues.

Pros & Cons

• Solid steel construction and plate brackets restore structural integrity to worn arms.
