Fits 2014-2018 Jeep Cherokee, front left lower. Delphi TC4003 is engineered with OE-focused dimensional and material analysis, and it is tested for temperature extremes and salt-spray exposure to support consistent performance in demanding conditions.

Key Features

• Aluminum control arm with casting/forged construction
• Standard replacement grade for direct service use
• Rubber bushings included
• Black finish with black bushing color
• Uncoated surface treatment
• Non-adjustable, grease-free design

Detailed Description

This Delphi suspension control arm is built for the front left lower position on the Jeep Cherokee and is identified by part number TC4003. The aluminum body and casting/forged construction provide a service-ready replacement format, while the rubber bushings help maintain the intended suspension connection point. Delphi applies OE-oriented dimensional and material analysis to improve part matching and fit consistency. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Use TC4003 when replacing a worn or damaged control arm on the Jeep Cherokee. The design is non-greaseable, pre-greased status is not specified, and mounting hardware is not included.

What It Helps Fix

• Excessive suspension play from worn bushings
• Clunking or looseness from a damaged control arm
• Uneven steering response caused by worn suspension joints
• Alignment instability after control arm wear
• Noise from deteriorated lower suspension components

Installation Notes

Verify fitment by year, make, model, and front left lower position before installation. Inspect related suspension components and alignment settings during replacement. Because this is a standard replacement control arm, confirm that the mounting points and bushing dimensions match the original part before service.

Quality Assurance

Delphi applies OE safety technology and aftermarket engineering practices to this suspension control arm. The part is tested for temperatures below -40 degrees C and above 120 degrees C, and it is exposed to 720 hours of salt spray to evaluate durability under harsh conditions.
