Delphi Suspension Control Arm and Ball Joint Assembly P/N:TC3985
Delphi Suspension Control Arm and Ball Joint Assembly P/N:TC3985
$92.99

Nail down precise steering and steady wheel location with the DELPHI control arm (P/N TC3985), a front left lower control arm and ball joint assembly that drops in for the 2016-2021 Honda HR-V. Delphi applies its OE steering expertise to this aftermarket unit, with extensive dimensional and material analysis to keep the OE and aftermarket part closely matched.

  • Tested to the extreme: validated for OE-level performance in temperatures below -40°C and above 120°C, plus 720 hours of salt-spray exposure.
  • Verified integrity: 100% crack detection and ultrasonic flaw detection help confirm materials match OE specifications.
  • Precision ball stud: studs are machined to micron tolerances for durability and smooth joint operation.
  • Built for consistency: robot welding delivers repeatable quality, and anti-corrosion protection is applied to each part for corrosion prevention and enhanced appearance.

The control arm positions the wheel and, through its integrated ball joint, allows the steering knuckle to pivot and travel with the suspension. Clunking over the front end, loose or wandering steering, and uneven tire wear can be signs the original arm or ball joint may need replacing; if a worn front left lower arm is the cause, this assembly replaces it. If you're weighing DELPHI control arm reviews, this unit carries Delphi's OE-grounded engineering.
