Key Features

• Rubber construction for suspension isolation and control
• Standard replacement grade for OE-style service
• Rear upper forward position
• 52.0 length, 12.2 inside diameter, 39.6 outside diameter
• Delphi dimensional and material analysis for OE-to-aftermarket compatibility
• Tested for temperature extremes below -40 C and above 120 C
• Exposed to 720 hours of salt spray during validation

Detailed Description

This Delphi suspension control arm bushing, part number TD5781W, is designed for rear upper forward placement and uses rubber construction to help maintain suspension geometry and reduce unwanted movement at the control arm. Delphi applies OE-focused engineering and validation methods to its aftermarket steering and suspension portfolio, including dimensional and material analysis to match the original application as closely as possible. For drivers servicing Buick LaCrosse, Buick Regal, or Chevrolet Malibu rear upper suspension points, TD5781W provides a direct replacement option built around the listed 12.2 mm inside diameter and standard replacement specifications.

This part cross-references Dorman - OE Solutions 524-215 for the same application.

What It Helps Address

• Excessive suspension play at the rear upper control arm
• Clunking or knocking from worn bushing material
• Uneven tire wear caused by loosened suspension geometry
• Steering or handling looseness related to rear suspension wear
• Vibration transfer from deteriorated rubber bushings

Installation Notes

Verify the rear upper forward position and confirm the 12 mm inside diameter before installation. Compare the old bushing’s length, inside diameter, and outside diameter against the listed dimensions to ensure proper seating in the control arm. Professional suspension service is recommended because worn bushings can affect alignment and overall rear suspension performance.

Quality Assurance

Delphi validates this bushing with temperature cycling from below -40 C to above 120 C and extended salt-spray exposure to evaluate durability in harsh conditions. The brand’s OE engineering background supports consistent fitment and material selection for applications such as Buick LaCrosse, Buick Regal, and Chevrolet Malibu. Part number TD5781W is built as a standard replacement suspension bushing for the specified rear upper applications.
