Detailed Product Overview

Delphi TC3842 is a bent, stamped steel control arm with black bushings and a painted finish for corrosion resistance. The assembly uses rubber bushings and a bolt-in design, and it is not pre-greased. Delphi subjects its steering and suspension parts to extreme temperature exposure and extended salt spray testing, then verifies dimensions and materials to support OE-style fit and function. If you are replacing a front right lower control arm on a Volkswagen Tiguan, Audi Q3, or Volkswagen Arteon, TC3842 provides a direct replacement option built around the original suspension layout.

This part cross-references Dorman OE Solutions 527-070 for the same application.

Common Problems This Part Can Address

• Clunking or knocking from the front suspension
• Excessive play in the front right lower control arm
• Worn or cracked rubber bushings
• Uneven tire wear caused by suspension looseness
• Steering instability or wandering at the front end

Installation Notes and Tips

Install TC3842 on the front right lower position only. Because mounting hardware is not included, reuse serviceable fasteners or source new hardware as needed. After installation, perform a wheel alignment to verify suspension geometry and steering response. Confirm vehicle application by year, make, model, and position before ordering.

Quality Assurance

Delphi uses OE-based engineering, dimensional checks, and material analysis for aftermarket steering and suspension components. The brand also tests parts through temperature extremes below -40 degrees C and above 120 degrees C, along with 720 hours of salt spray exposure, to evaluate durability under demanding conditions.
