$129.99

Get a smooth, controlled ride and steady steering with the Delphi control arm TC5217, a front left lower control arm and ball joint assembly built on Delphi's OE safety technology fitted to millions of vehicles worldwide. It drops in as a direct-fit replacement for the 2002-2007 Buick Rendezvous and 2001-2005 Pontiac Aztek — the part many shoppers search for as a 2003 Buick Rendezvous lower control arm or a Pontiac Aztek control arm. See the Buyer's Guide tab for engine-level fitment details.

  • Tested to the extreme: withstands temperatures below -40°C and over 120°C and endures 720 hours of salt spray for OE-level performance.
  • Verified materials: 100% crack detection and ultrasonic flaw detection help ensure the material matches OE specifications.
  • Precision ball stud: studs machined to micron tolerances for durable, smooth joint operation.
  • Built to last: robot welding for consistent quality, plus anti-corrosion protection applied to each part for corrosion prevention and enhanced appearance.

Worn control arm bushings or a loose ball joint can cause clunking, uneven tire wear, or wandering steering; if the original front left lower arm is the cause, this assembly replaces it.

What are signs my lower control arm needs replacing?

Clunking over the front end, uneven tire wear, or loose or wandering steering can point to worn bushings or a failing ball joint. Diagnose the cause before replacing.
