Detailed Product Overview

Delphi TC1918 is engineered for the rear upper forward suspension location and is built to match OE-style dimensional and material requirements. Delphi applies extensive dimensional and material analysis to support proper compatibility between the original part and the aftermarket replacement, while its OE-focused testing includes exposure to extreme temperatures and prolonged salt spray. This makes the TC1918 a practical choice for BMW rear suspension repair where control arm wear can affect alignment, ride quality, and handling response. This part cross-references Beck/Arnley 102-6631 for the same application.

Common Issues This Part Can Address

• Rear suspension clunking or knocking from worn bushings
• Excessive play in the rear upper forward control arm
• Uneven tire wear caused by suspension looseness
• Alignment instability after suspension wear or inspection failure
• Restoring rear suspension geometry on BMW 320i, 328i, and 335i models

Installation Notes and Tips

Install Delphi TC1918 in the rear upper forward position only. Because the ball joint is not included and mounting hardware is not included, verify the condition of related components before installation and transfer or source any required service parts separately. A professional alignment is recommended after suspension work, especially on BMW 128i, 135i, 328i xDrive, and 335i xDrive applications.

Quality Assurance

Delphi backs its aftermarket steering and suspension portfolio with OE-based engineering and validation. TC1918 is tested for temperature extremes below -40 degrees C and above 120 degrees C, and for 720 hours of salt spray exposure to help verify durability in harsh operating conditions.
