2002-2002 Audi A4 Front Lower Forward Control Arm with Ball Joint Pair (8th Vin Digit E)

  • New

These replacement front lower control arms are just what you need to bring back the safety and integrity of your vehicle's suspension and steering.

Specifications:

  • Comes as a PAIR
    • Fits both LH (Driver Side) & RH (Passenger Side) FRONT LOWER FORWARD
  • Includes new ball joints and bushings
  • Replaces dealer part numbers: 8E0 407 151 M, 8E0 407 151 R, 8E0407151M, 8E0407151R
  • Direct fit replacements
  • Built to strict quality control standards

Worn ball joints or loose rear bushings can cause excessive front tire wear, popping or creaking in the front end, extra play in the steering system, and pose a serious safety concern. Replace that heavily rusted, rotted, or damaged front upper control arm with the loose bushings or worn ball joints with our high quality all in one replacements.

One way to diagnose a loose, or warn ball joint on a control arm, is to jack the car up, so the wheel is off of the ground, then have someone try to move the wheel in and out. While they are moving the wheel check the ball joint and bushings for play, if it is moving you probably need to replace it.

Lifetime Warranty
