TRQ Front Upper Control Arm & Ball Joint Passenger Right - Direct Fit

In this review of the TRQ front upper control arm and ball joint for the passenger right side, the bottom line is simple: this assembly is for owners of compatible Mercedes-Benz C, CLK, E and SLK models who need a practical, vehicle-specific replacement that restores steering geometry without aftermarket guesswork. The reviewer found the unit to be a true direct fit OE replacement that matches original mounting points and reference numbers, making it the most straightforward option when a worn control arm or ball joint needs replacement.

Key Features

• Direct Fit: Designed to match OE mounting points so installation aligns with factory geometry and reduces adjustment time.
• Complete Assembly: Includes the control arm and ball joint in one unit to simplify swap-out and avoid hunting for separate parts.
• Vehicle Specific Fitment: Fitment listings cover many Mercedes-Benz C, CLK, E and SLK years to help confirm compatibility before purchase.
• OE Reference Match: Cross-referenced to multiple OE numbers like 1633330001 and 2023304907 so technicians can verify fit against original parts.
• Aftermarket Cross-References: Multiple aftermarket reference numbers are listed to aid parts lookups and warranty or return checks.

Who It's For

This part is aimed at DIY mechanics, independent shops and Mercedes owners who prefer a like-for-like replacement rather than a generic or adjustable aftermarket arm. It suits those repairing the front passenger upper suspension on model years listed in the fitment notes and who want a ready-to-install assembly.

Owners with performance or modified suspensions, or those who need adjustable alignment arms, should look elsewhere; this product is intended as an OE-style replacement rather than a performance upgrade.

Pros & Cons

Pros

• Fits and aligns with original mounting locations, reducing installation time and alignment headaches.
• Arrives as a single assembly so the ball joint and arm match and no additional sourcing is needed.
• Good value compared with dealer pricing, with several customers noting cost savings.

Cons

• Some customers reported issues with the ball joint on a small number of units, so inspection before installation is advisable.
