Detailed Description

This Delphi leaf spring shackle bushing, part number TD4733W, is designed for rear suspension mounting points where the shackle connects to the frame or rear upper location. Delphi applies OE-level testing and dimensional checks to help ensure the bushing matches the intended application, including exposure to extreme temperatures and salt spray conditions during validation. This makes TD4733W a practical choice for restoring rear suspension connection points on vehicles such as Chevrolet Colorado, GMC Canyon, and Chevrolet S10.

This part cross-references GM 15963452 for the same application.

What It Helps Address

• Rear suspension looseness at the shackle mounting point
• Clunking or rattling from worn leaf spring bushings
• Excess movement between the leaf spring shackle and frame
• Uneven rear suspension response caused by deteriorated rubber
• Fitment issues when replacing a worn OE-style rear bushing

Installation Notes and Tips

Verify the position on your vehicle before ordering, since this bushing is listed for rear to frame and rear upper applications depending on model. Confirm the inside diameter, outside diameter, and height against the original part to ensure proper installation. For fitment-specific service, use the application details for your Chevrolet Colorado, GMC Canyon, Hummer H3, or other listed vehicle before beginning suspension work.
