Delphi TC7618 Suspension Control Arm - Rear Lower Rearward

Delphi TC7618 Rear Lower Rearward Control Arm

The Delphi TC7618 is a stamped steel suspension control arm for the rear lower rearward position on select Smart Fortwo models. Built as a standard replacement part, it includes bushings and follows Delphi’s OE-focused dimensional and material analysis for proper fit and consistent suspension geometry.

Key Features

• Fits 2005-2014 Smart Fortwo, rear lower rearward
• Stamped steel construction for structural strength
• Black steel finish with gray and black bushing color
• Rubber bushings included
• Standard replacement grade with performance-grade construction

Detailed Description

Delphi TC7618 is engineered for the rear lower rearward suspension position on the Smart Fortwo, covering model years 2005 through 2014. The arm uses stamped steel construction and rubber bushings to restore rear suspension support and maintain alignment-related geometry in the rear lower control arm location. Delphi applies OE-based testing and dimensional analysis to help ensure the aftermarket part matches the original application closely. This part cross-references Mercedes-Benz A4513500029 and A4513500129 for the same application.

Common Problems This Part Can Address

• Excessive rear suspension play or looseness
• Clunking or knocking from the rear lower suspension area
• Uneven tire wear related to worn rear control arm bushings
• Handling instability caused by worn suspension pivot points
• Restoring rear suspension alignment after bushing or arm wear

Installation Notes and Tips

Verify the rear lower rearward position before installation and compare the original arm length and mounting-hole spacing to the replacement part. Because mounting hardware is not included, reuse or source the correct hardware as needed. After installation, perform a professional wheel alignment to confirm rear suspension geometry on the Smart Fortwo.

Quality Assurance

Delphi subjects its OE-style steering and suspension components to extreme temperature and salt-spray testing, along with dimensional and material checks, to support consistent fit and durability in aftermarket service. Delphi TC7618 is built to meet standard replacement needs for the Smart Fortwo rear lower rearward suspension position.
