Detailed Description

Delphi TC8389 is a rear left trailing arm for suspension systems on the 2016-2022 Fiat 500X, 2017-2022 Jeep Compass, and 2015-2022 Jeep Renegade. Delphi applies OE-focused engineering and material analysis to help ensure the replacement part matches the original application requirements. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Part Helps Address

• Rear suspension looseness or instability
• Excessive play from worn trailing arm bushings
• Uneven rear wheel tracking
• Clunking or knocking from the rear suspension
• Corrosion-related replacement needs on the original arm

Installation Notes and Tips

• Install in the rear left position only.
• Mounting hardware is not included.
• Inspect adjacent bushings, fasteners, and suspension links before installation.
• Verify vehicle year, make, model, and rear-left application before ordering.
• Professional alignment is recommended after suspension component replacement.

Quality Assurance

Delphi subjects its OE-style aftermarket steering and suspension components to temperature extremes below -40 C and above 120 C, along with extended salt-spray exposure and dimensional/material analysis. That testing supports fit consistency and corrosion resistance expectations for daily-driven vehicles such as the Fiat 500X, Jeep Compass, and Jeep Renegade.
