Delphi Suspension Control Arm and Ball Joint Assembly P/N:TC7255
$217.99

Keep the rear suspension precisely located with the DELPHI control arm, part number TC7255 — a rear left upper control arm and ball joint assembly that installs as a direct-fit replacement for the listed applications: the 2003-2008 Infiniti FX35, the 2003 Infiniti FX45, and the 2007-2008 Infiniti FX45 (All engines).

  • Tested to extremes: withstands temperatures below -40°C and above 120°C plus 720 hours of salt-spray exposure, with dimensional and material analysis for close compatibility between the OE and aftermarket part.
  • Verified materials: 100% crack detection and ultrasonic flaw detection help the materials match OE specifications.
  • Precision joint: ball studs machined to micron tolerances for durability and smooth joint operation.
  • Built to last: robot-welded for consistent quality, with anti-corrosion protection applied for corrosion prevention and enhanced appearance.

This assembly positions the rear wheel and lets the suspension move through its travel while the integrated ball joint handles articulation. Worn bushings or a loose ball joint may show up as clunking over bumps, uneven tire wear, or imprecise handling — if the original left upper arm is the cause, this replaces it. Country of origin: China.

Frequently Asked Questions

What vehicles does the DELPHI TC7255 control arm fit?

It fits the 2003-2008 Infiniti FX35, the 2003 Infiniti FX45, and the 2007-2008 Infiniti FX45 (All engines). Check the Buyer's Guide tab to confirm your vehicle.

Where does this Infiniti FX35 control arm mount?

The catalog lists it in the rear left upper position, so it serves as the rear driver-side upper control arm on the listed applications.

Does this control arm include the ball joint?

Yes. The ball joint is integrated into the arm as a single unit, so it is not sold separately from the arm.

What are signs this control arm may need replacing?

Clunking or knocking over bumps, uneven tire wear, or vague, imprecise handling can point to worn bushings or a loose ball joint. Diagnose the cause before replacing.

Is this DELPHI control arm well made?

Delphi applies its OE engineering to its aftermarket steering line; each arm passes 100% crack and ultrasonic flaw detection plus salt-spray testing — details buyers often check in DELPHI control arm reviews.
