Installation Notes
TD4021W is a pressed-in bushing, so proper removal and installation tools are required. Inspect the control arm, mounting bore, and surrounding suspension components before installation, and verify the exact position on your vehicle using the application tab because fitment varies by model and side. For Jeep Compass, Jeep Patriot, and Dodge Caliber applications, confirm whether your vehicle uses the front lower forward or front left/right lower location before ordering.
Quality Assurance
Delphi applies OE-focused engineering and testing to its aftermarket steering and suspension portfolio. This bushing is evaluated for temperature extremes below -40 degrees C and above 120 degrees C, and it is exposed to 720 hours of salt spray testing to help verify durability in demanding service conditions.
