In the event of a failure of Audi A4 tie rod ends or assemblies, your Audi parts specialist has the solution. Some original Audi A4 tie rods have a link in between the ball joint and the tie rod end which is embedded in rubber (see OEM Version in Image 2). Thanks to power steering, drivers no longer feel the great force caused when turning the steering wheel. These forces create significant surface pressure on the Audi A4 tie rod end ball pin in the bearing shell. Continuous or extreme dynamic strain as well as corrosion on the tie rod end can cause Audi A4 tie rod end failure. Audi A4 tie rod end failure reveals itself by squeaking and rattling along with a loose steering feel.
