TRQ Front Left Lower Rearward Control Arm with Ball Joint - Fits

In this review of the TRQ front left lower rearward control arm with ball joint, the reviewer focuses on fitment and practical value for owners of select Mercedes-Benz models. This control arm is aimed at drivers who need a direct replacement for a damaged lower rearward control arm and want a unit that matches original geometry. The single biggest reason to consider it is the vehicle-specific aluminum construction and included ball joint, which together offer a close OEM-like fit and a lower cost alternative to dealer parts.

Key Features

• Vehicle Specific Fit: Fits specific Mercedes-Benz C300, C350, E350 and E400 front driver side lower rearward locations to minimize fitment issues during installation.
• Aluminum Construction: Lightweight aluminum helps preserve suspension geometry while resisting corrosion compared with untreated steel parts.
• Includes Ball Joint: Delivered with a ball joint installed so the assembly is ready to mount without sourcing additional components.
• Machined Ball Joint Mount: A machined mounting surface on the ball joint improves alignment precision and helps the joint seat correctly in the knuckle.
• Bushings Included: Supplied with bushings to restore mounting points and reduce immediate additional purchases when replacing the control arm.

Who It's For

This part is best for Mercedes-Benz owners who need a like-for-like replacement for the front left lower rearward control arm on compatible C300, C350, E350 and E400 models. Independent shops and DIY mechanics who value exact-fit components will appreciate the included ball joint and the aluminum construction for a close match to original equipment behavior.

Drivers who require adjustable suspension components or a fully greasable ball joint should look elsewhere, since this control arm is not adjustable and the ball joint is not greaseable. It is not intended for vehicles outside the listed model years or for performance-modified suspension setups where different geometry is required.

Pros & Cons

Pros

• Vehicle-specific design reduces the chance of mismatched fit and saves installation time.
• Aluminum construction resists corrosion and keeps weight down compared with heavier alternatives.
• Includes the ball joint and bushings so the assembly is ready to install.
• Generally reported as good value and matching original parts in fit and finish.

Cons

• Some customers have reported ball joint damage, so long-term durability of the joint may vary.
• The ball joint is not greaseable, which limits serviceability compared with rebuildable joints.

Specifications

Our Verdict

The TRQ front left lower rearward control arm is a practical, cost-conscious replacement for owners of compatible Mercedes-Benz models who need a proper fit and OEM-like geometry. It delivers solid value through aluminum construction and a ready-to-install assembly, but buyers should be aware the ball joint is not greaseable and a few users reported joint issues over time. Overall, it is a sensible choice for standard replacements and routine repairs.
