TRQ Front Upper Control Arm w Ball Joint Left LH - Direct Fit

In this review of the TRQ Front Upper Control Arm w Ball Joint Left LH the bottom line is clear: this is a practical, vehicle-specific replacement for owners of rear-wheel drive Mercedes E and CLS models who need a direct-fit suspension arm without OEM pricing. The reviewer finds it most useful for DIY mechanics and independent shops because it installs like an OE replacement and uses familiar OE reference numbers for cross-checking fitment. The review highlights fit, ease of installation, and value while noting the one area buyers should inspect carefully: the ball joint.

Key Features

• Direct Fit: Designed to match the original mounting points for a straightforward swap into compatible Mercedes E and CLS front left upper positions.
• OE Replacement Assembly: Includes the control arm and ball joint as a single assembly to reduce labor and alignment variables during installation.
• Vehicle Specific Fitment: Fitment listings and OE reference numbers let buyers confirm compatibility with specific 2003-2011 RWD models before purchase.
• Multiple Cross References: Supplied aftermarket and OE reference numbers make it easier to verify part equivalence with service manuals and parts catalogs.
• Value for Money: Offers a cost-effective alternative to dealer parts while maintaining correct geometry and mounting for safe suspension operation.

Who It's For

This control arm is aimed at owners of 2003-2011 Mercedes E350, E320, E500, E550, E55 AMG and CLS models with rear-wheel drive who want a direct-fit replacement for the front driver side upper control arm. It suits experienced DIYers, independent mechanics, and restoration projects where matching OEM fit and function matters.

Those who should look elsewhere include owners of four-wheel drive or non-listed model years, and anyone who prefers an OEM dealer part for warranty or brand-new original supplier backing. Also consider a full suspension inspection before buying if multiple suspension components are worn.
