Detailed Description

Delphi TC3980 is engineered as a direct replacement front left lower control arm assembly for Nissan Frontier and Nissan Xterra models listed above. Delphi applies OE-focused dimensional and material analysis to help maintain proper suspension geometry and part-to-vehicle compatibility. The assembly uses stamped steel construction, black painted finish, rubber bushings, and a chloroprene rubber dust boot for the ball joint. It is non-adjustable, non-greaseable, and configured for power steering applications.

This part number, TC3980, is a practical choice when replacing a worn lower control arm on a 2014-2019 Nissan Frontier or a 2014-2015 Nissan Xterra. The assembly includes the ball joint, bushings, dust boot, and mounting hardware, reducing the number of separate components needed during service.

Common Repair Uses

• Front-end clunking or knocking from a worn lower control arm
• Excessive play from a failing ball joint
• Cracked, torn, or deteriorated suspension bushings
• Uneven tire wear caused by loose front suspension components
• Restoring stable steering response on Frontier and Xterra models

Installation Notes and Tips

Install TC3980 on the front left lower position only. Verify vehicle year, make, model, and suspension configuration before installation, and inspect adjacent components such as the tie rod ends, sway bar links, and alignment settings while the front suspension is apart. Because this is a press-in ball joint design, proper service tools and a post-installation wheel alignment are recommended after replacement.

Quality Assurance

Delphi subjects steering and suspension components to extreme temperature and corrosion testing, including exposure below -40 degrees C, above 120 degrees C, and extended salt-spray testing. The brand also uses dimensional and material analysis to support OE-style fit and performance for aftermarket replacement parts.
