TRQ Lower Control Arm LH Left Hand Driver Side for Ford Mazda Mercury

In this review the TRQ Lower Control Arm LH is evaluated for owners replacing a worn front lower control arm on compatible Ford, Mazda and Mercury trucks. The bottom line: it is a direct-fit, OE replacement assembly that most DIYers and independent mechanics will choose because it replaces both the control arm and ball joint in one unit, matching original geometry and saving installation time. The review focuses on fitment, build quality and real-world notes from owners who used it on Ranger, Explorer and B3000/B4000 models.

Key Features

• Direct Fit: Installs as an OE replacement without modification on listed vehicle applications, reducing shop time and alignment corrections.
• Control Arm with Ball Joint: Includes the lower control arm and ball joint assembled, so users replace both wear items in one procedure.
• Vehicle Specific Fitment: The listing provides fitment details so buyers can confirm compatibility with Ranger, Explorer, Mountaineer and Mazda B series models before ordering.
• OE Reference Numbers: Uses known OE reference numbers such as 1F7034320 and 2L2Z3079BA, which helps match it to original parts for correct replacement.
• Aftermarket Cross References: Multiple aftermarket reference numbers are provided, aiding mechanics who compare alternatives and service catalogs.
• Front Driver Side Lower: Built specifically for the left hand driver side lower suspension position on the compatible model years, ensuring correct orientation.

Who It's For

This control arm is aimed at owners of 1995-2011 Ford Rangers, 1995-2005 Explorers, 1997-2001 Mercury Mountaineer and 2001-2009 Mazda B3000/B4000 trucks who need a cost effective, direct-fit replacement for the front driver side lower control arm. It suits DIY mechanics comfortable with suspension work and independent shops that want a ready-to-install assembly.

Those who should look elsewhere include owners of vehicles outside the listed years or models and buyers who prefer to replace only the ball joint instead of the entire arm; the part is designed as a full arm and ball joint assembly rather than a separate serviceable ball joint.

Pros & Cons

Pros

• Direct OE-style fit that most buyers report matches original parts and is straightforward to install.
• Includes ball joint and arm together, saving time versus sourcing two separate components.
• Clear fitment and OE cross reference information helps ensure correct selection for listed vehicles.

Cons

• Some customers have reported ball joint issues, so longevity may vary and inspection after installation is advised.
