Front Left Lower Control Arm with Ball Joint for 2010-2017 Buick

In this review of the Front Left Lower Control Arm with Ball Joint and Bushing Assembly the bottom line is straightforward: this replacement part is for owners of compatible Buick and Malibu models who need a durable, OEM-exceeding chassis component that installs without exotic tools. The reviewer found the piece especially suited to those who value corrosion-resistant aluminium construction and a pre-greased joint for smoother initial operation. Fit and function are the single biggest reasons to consider this part, since it matches listed OE interchange numbers and ships as a complete control arm assembly for faster repair.

Key Features

• Vehicle Compatibility: Built specifically to fit 2010 Buick Allure, 2010-2016 LaCrosse, 2011-2017 Regal and 2013-2016 Malibu models, minimizing guesswork when ordering.
• Pre-greased Joint: Arrives pre-greased to reduce initial wear and make the first weeks of operation noticeably smoother.
• Aluminium Body: The aluminium material helps reduce weight compared with steel while resisting corrosion in normal road conditions.
• OE Interchange Numbers: Lists RK641500, CMS501125, 521-951 and 23354433 so installers can confirm compatibility with existing parts catalogs.
• Quality Standards: Manufactured under IATF 16949 and ISO 9001 processes to exceed OEM standards for repeatable fit and performance.
• Warranty Support: Backed by a 3 year / 36,000 mile limited warranty from installation for added peace of mind.

Who It's For

This control arm is best for DIY mechanics, independent shops and vehicle owners maintaining a compatible Buick LaCrosse, Allure, Regal or Malibu who want a direct-fit replacement that reduces downtime. The pre-greased ball joint and included bushing assembly make it a straightforward swap for technicians comfortable with front suspension work.

Those who should look elsewhere include owners of non-listed models or drivers seeking an adjustable performance arm; this part is a direct replacement built to OEM-style geometry rather than an adjustable aftermarket performance piece.
