Delphi Suspension Control Arm and Ball Joint Assembly P/N:TC2548
Delphi Suspension Control Arm and Ball Joint Assembly P/N:TC2548
$69.99

Restore precise steering and a stable ride with the Delphi control arm and ball joint assembly, part number TC2548 — a front left lower unit that installs as a direct-fit replacement on the 1986-1994 Nissan D21 and the 1993-1994 Nissan Pathfinder, and also fits the Nissan Pickup (see the Buyer's Guide tab for the full application list). It locates the front wheel and pairs the lower arm with an integrated ball joint, so one part addresses worn bushings and a loose or noisy joint together. If a failed lower ball joint or a cracked bushing is behind clunking over bumps, uneven tire wear, or wandering steering, this Delphi unit replaces it.

  • OE-matched materials: every arm undergoes 100% crack detection and ultrasonic flaw detection so its materials match OE specifications.
  • Precision ball stud: the ball studs are machined to micron tolerances for durability and smooth joint operation.
  • Robot-welded: robot welding delivers consistent performance and quality.
  • Anti-corrosion protection: applied to each part for corrosion prevention and enhanced aesthetics, and validated below -40°C, above 120°C, and through 720 hours of salt spray.

Sold as a Nissan Pathfinder lower control arm with the ball joint already installed, it saves the labor of pressing a joint into a bare arm; this listing is the front left lower unit, so order the opposite side separately if you're replacing both.

Frequently Asked Questions

Will this fit my Nissan Pathfinder control arm application?

Yes — it's listed for the 1993-1994 Nissan Pathfinder, plus the 1986-1994 Nissan D21 and the Nissan Pickup. Check the Buyer's Guide tab to confirm your exact year.

What position is TC2548?

It's the front left lower control arm with an integrated ball joint. This listing covers one side; order the opposite side separately if you're replacing both.

Does it include the ball joint?

Yes. The ball joint comes pre-assembled in the arm, so you don't have to press a separate joint into a bare control arm.

What are the signs I need a new lower control arm or ball joint?

Clunking over bumps, uneven or accelerated tire wear, and loose or wandering steering can point to a worn arm or ball joint. Diagnose the cause before replacing.

How is this Delphi control arm made?

Each unit gets 100% crack and ultrasonic flaw detection, ball studs machined to micron tolerances, robot welding, and anti-corrosion protection, validated across extreme temperatures and 720 hours of salt spray.
