Delphi TD580W Suspension Control Arm Bushing - Front Lower Inner Rearward

OE-Style Suspension Control Arm Bushing

Delphi TD580W is a rubber suspension control arm bushing built as a standard replacement for the front lower inner rearward position. It is engineered with press-fit mounting and OE-focused dimensional control for a precise service replacement on applications such as Honda Civic and Acura models that use this bushing location.

Delphi applies OE-level material and dimensional analysis to help ensure proper fit between the original part and the aftermarket replacement. The TD580W is built to handle demanding temperature extremes and corrosion exposure, making it a practical choice for restoring suspension joint integrity.

Detailed Description

The Delphi TD580W suspension control arm bushing is intended for front lower inner rearward suspension service where rubber isolation and stable control arm location are required. Its press-fit design and OE-based dimensional analysis support accurate replacement in vehicles that use this bushing specification, including Honda Civic and Acura applications. Delphi’s OE background is reflected in the material selection and validation process used for this part number, TD580W.

This part cross-references Honda 54570AX600 for the same application.

What It Helps Address

• Clunking or knocking from worn control arm bushings
• Excessive suspension play at the front lower inner rearward mount
• Steering looseness caused by deteriorated rubber isolation
• Uneven tire wear related to suspension alignment movement
• Vibration transfer from worn suspension bushings

Installation Notes and Tips

TD580W is a press-fit bushing, so proper removal and installation tools are required to service the control arm correctly. Inspect the control arm, mounting bore, and surrounding suspension components before installation, and verify the replacement matches the original dimensions and position. Confirm vehicle application by year, make, model, and suspension location before ordering.

Quality Assurance

Delphi validates this bushing through dimensional and material analysis, along with environmental testing for heat, cold, and salt exposure. The OE-focused design approach supports consistent replacement quality for front suspension service.
