TRQ Front Left Lower Rearward Control Arm with Ball Joint - Direct Fit

In this review the TRQ Front Left Lower Rearward Control Arm with Ball Joint is evaluated as a direct-fit OE replacement for select Cadillac ATS and CT4 models. The bottom line: it is aimed at owners who need an affordable, vehicle-specific suspension arm that installs without modification and restores proper geometry. Installers will appreciate the straightforward fitment and integrated ball joint, while buyers seeking a heavy-duty OEM equivalent should weigh mixed notes about long-term durability.

Key Features

• Direct Fit: Ships as a vehicle-specific assembly that installs in place of the original unit to avoid custom modifications or adapter parts.
• OE Replacement Assembly: Includes the control arm and ball joint as a single unit so the suspension geometry and articulation match the intended design.
• Wide Compatibility: Labeled to fit multiple model years of the Cadillac ATS and CT4 front driver side lower rearward position for Rear Wheel Drive variants.
• Aftermarket Reference Numbers: Cross-referenced to common aftermarket numbers such as 20768758 and 23462008 for easier part lookup and comparison.
• Ease of Installation: Customers commonly report that the arm is straightforward to fit, saving time during a brake or suspension service.

Who It's For

This control arm is best for DIY mechanics, independent shops, and Cadillac owners who need a like-for-like replacement on the front driver side lower rearward position for rear wheel drive ATS models (2013-2019) and CT4 (2020-2021). It is particularly useful when the original ball joint or arm shows wear and the vehicle requires restored alignment and handling.

Those who should look elsewhere include owners seeking an upgraded performance or heavy-duty aftermarket arm built for aggressive driving or track use, since at least one customer noted the firmness and long-term durability differ from heavier OEM pieces.
