Help steady your steering with the Delphi control arm for the front right lower corner, MPN TC1227. This control arm and ball joint assembly bolts in as a direct-fit replacement for the 1997-2003 BMW 540i and the 2000-2003 BMW M5, locating the wheel and letting the suspension pivot smoothly through its travel. See the Buyer's Guide tab for engine details.

  • OE-derived engineering: Delphi applies its OE steering expertise to the aftermarket, with extensive dimensional and material analysis for close OE-to-aftermarket compatibility.
  • Validated to the extreme: tested below -40°C and above 120°C and exposed to 720 hours of salt spray for OE-level performance.
  • Quality-checked build: 100% crack detection and ultrasonic flaw detection confirm materials match OE specifications; robot welding gives consistent quality.
  • Precision joint: ball studs are machined to micron tolerances for durability and smooth joint operation, with anti-corrosion protection applied to each part.

Worn control arm bushings or a loose ball joint can cause clunking on acceleration or over bumps, uneven tire wear, and wandering steering — if this arm is the cause, TC1227 replaces it.

Frequently Asked Questions

Does this Delphi control arm fit my BMW?

TC1227 is a direct-fit replacement for the 1997-2003 BMW 540i and the 2000-2003 BMW M5. Check the Buyer's Guide tab to confirm it matches your vehicle.

What position is this control arm and ball joint assembly?

Do I need a 2000-2003 BMW M5 control arm on both sides?

This listing is for one front right lower arm. Replacing the matching left side at the same time is a good practice for balanced, even suspension wear.

Each arm gets 100% crack detection and ultrasonic flaw detection to confirm materials meet OE specifications, plus robot welding and anti-corrosion protection.

What are signs this control arm may need replacing?

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