Detailed Description

Delphi TC3746 is engineered for the front left lower suspension position on select Ford Transit vans. Delphi applies OE-focused dimensional and material analysis to help ensure proper fit and consistent suspension performance, and the part is tested across extreme temperature and corrosion conditions to support durability in demanding service. If you need a Ford Transit-150 front left lower control arm or a replacement lower control arm for a Ford Transit-350 HD, this part number TC3746 is built for that application.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Front-end looseness or wandering caused by worn control arm bushings
• Uneven tire wear related to suspension geometry changes
• Clunking or knocking from a deteriorated lower control arm assembly
• Steering pull or unstable handling on Ford Transit vans
• Suspension noise from cracked or fatigued rubber bushings

Installation Notes and Tips

Install TC3746 in the front left lower position only. Mounting hardware is not included, so inspect existing fasteners and related suspension components before installation. Because the ball joint is not included, verify the condition of the mating joint and replace any worn companion parts as needed. A professional alignment is recommended after suspension work on a Ford Transit-250, Transit-350, or other listed Transit model.

Quality Assurance

Delphi uses OE-based engineering and material analysis for aftermarket steering and suspension parts. This control arm is tested for temperature extremes and salt-spray exposure to support corrosion resistance and long-term service in everyday driving conditions.
