FAQs

Does this control arm come with a ball joint?

No, the TC1428 is supplied individually and does not include a ball joint.

Can I use this on both sides of the car?

Yes, this part is designed to fit both the left and right sides of the front axle.

Do I need to replace both control arms at the same time?

It is highly recommended to replace suspension components in pairs to maintain balanced handling and even tire wear.

What is the primary sign that I need to replace my control arm?

Common symptoms include unresponsive steering, a vibrating steering wheel, or clunking sounds when driving over bumps.

Is a professional alignment required after fitting this part?

Yes, any work involving the suspension geometry necessitates a professional wheel alignment to ensure safety and prevent uneven tire wear.

What are the dimensions of the TC1428?

The dimensions are 380mm in length, 350mm in width, and 60mm in height.

Troubleshooting

Vehicle continues to pull to one side after installation

Verify that a professional alignment was performed and check tire pressure across all wheels.

Clicking or clunking noise persists

Inspect the ball joint and sway bar links, as these were not replaced with the control arm and may be worn.

Difficulty aligning the arm with the chassis mount

Ensure the vehicle is level and that the suspension is not under an uneven load; check for any bent subframe components.

Pros and Cons

Pros

  • Meets strict OE manufacturing specifications
  • Restores vehicle steering and handling stability
  • Fits both driver and passenger sides for versatility
  • High-quality build for long-term reliability

Cons

  • Ball joint not included with this unit
  • Requires professional alignment after installation
  • Limited to specific lower outer mounting positions

Setup, Compatibility & Care

Before installation, ensure the vehicle is safely supported on jack stands and the front wheels are removed. Because the TC1428 does not include a ball joint, you must inspect your existing ball joint for wear or purchase a new one to install alongside this arm. Always use the manufacturer-recommended torque specifications for all mounting bolts to prevent premature failure. Post-installation, it is mandatory to perform a professional four-wheel alignment to ensure the steering geometry is within factory tolerances. For maintenance, periodically inspect the bushings for signs of cracking or excessive play during routine oil changes to ensure longevity.
