TRQ Rear Left Lower Control Arm with Ball Joint - Direct Fit

In this review the TRQ Rear Left Lower Control Arm with Ball Joint is assessed for owners of 2009-2012 Ford Escape and 2009-2011 Mercury Mariner who need a direct OE-style replacement. The bottom line: it is a straightforward, vehicle-specific control arm assembly that replaces the factory unit and restores rear suspension geometry without modification. The reviewer found the fitment information and OE reference alignment helpful, and the unit's construction and included bushings make it a practical choice for routine suspension repair or a budget-conscious rebuild.

Key Features

• Direct Fit: Installs without alteration on compatible rear driver side lower locations, saving installation time and effort.
• OE Replacement Assembly: Combines the control arm and ball joint in one unit so users replace both wear items at once for consistent suspension performance.
• Vehicle Specific Fitment: Clear fitment guidance for 2009-2012 Ford Escape and 2009-2011 Mercury Mariner reduces the risk of ordering the wrong part.
• Steel Construction: The steel control arm provides the familiar strength and stiffness expected for rear lower suspension components.
• Bushings Included: Supplied bushings mean fewer separate parts to source during installation and help restore original ride characteristics.
• Reference Numbers: Multiple OE and aftermarket reference numbers are provided to verify compatibility with existing parts.

Who It's For

This control arm is aimed at DIY mechanics, independent repair shops, and owners servicing a compatible Ford Escape or Mercury Mariner who want a cost-effective direct replacement for a worn rear lower control arm and ball joint. It is especially useful when the goal is to restore alignment and handling without paying dealer prices.

Drivers who need adaptors, greaseable fittings, or adjustable geometry should look elsewhere, since this assembly is non-greaseable and non-adjustable. Also, if a specialized heavy-duty or performance upgrade is required, an aftermarket performance arm would be a better match.

• Included bushings and integrated ball joint remove the need to source multiple parts separately.
• Multiple reference numbers help verify compatibility with factory replacements.
• Steel construction offers expected durability for standard driving conditions.

Cons
