Front Right Lower Control Arm with Ball Joint for GLK350/GLK250

In this review of the Front Right Lower Control Arm with Ball Joint, the bottom line is simple: this is a practical OE-style replacement for owners of 2010-2015 Mercedes-Benz GLK350 and 2013-2015 GLK250 who need a direct-fit, vehicle-specific suspension arm that restores steering geometry without a major overhaul. The reviewer found it best for DIY mechanics and independent shops seeking an affordable, matching replacement that aligns with the original equipment reference numbers and installs in place of the worn passenger side lower forward arm.

Key Features

• Direct Fit: Designed to match the original mounting points so installation is straightforward for mechanics familiar with suspension work.
• OE Replacement Assembly: Includes the control arm and ball joint as a single unit to reduce compatibility guesswork when replacing the forward lower right suspension component.
• Aluminum Construction: The control arm material offers corrosion resistance and a weight advantage over steel while maintaining factory-style strength.
• Vehicle Specific: Fitment notes for 2010-15 GLK350 and 2013-15 GLK250 help buyers confirm compatibility before purchase.
• Bushings Included: Ships with bushings installed to simplify the swap and help restore correct suspension alignment.

Who It's For

This part suits owners of Mercedes-Benz GLK models who need a passenger-side lower forward control arm that matches OE reference numbers such as 2043308211 and aftermarket cross-references. It is a good option for independent shops and confident DIYers who can perform front suspension removal, ball joint torqueing, and alignment checks.

Customers who want a lifetime-lubricated, adjustable arm should look elsewhere, as this unit is not greaseable or adjustable; it is intended as a straightforward OE-style replacement rather than an upgrade performance part.

Pros & Cons

Pros

• Direct fit design reduces installation time by matching factory mounting locations.
• Includes both control arm and ball joint for a complete OE-style replacement.
• Aluminum material helps resist corrosion and keeps unsprung weight lower than steel alternatives.
• Ships with bushings to simplify the replacement process and help maintain alignment.

Cons

• Ball joint is not greaseable, and some users have reported ball joint issues over time, so longevity may vary with driving conditions.
• Not adjustable, so alignment must be corrected with suspension alignment procedures rather than on-arm adjustment.

Our Verdict

This control arm is a sensible, value-focused replacement for GLK350 and GLK250 owners who need a direct-fit passenger-side lower forward assembly.
