HOW TO SET UP A MOOG SUSPENSION ARM

Xenon headlights produce a bright and clear light which provide a better view of the road. In order not to dazzle oncoming traffic, the adjustments of the Xenon headlight height is very important. A vehicle with mechanical suspension varies in height due to the load in the passenger compartment. This can result in an upward light beam that can dazzle oncoming traffic.

With the information received from the right height sensor, the headlights move up and down in order to cast the beam on the road at all times.

When to replace a suspension arm?

There can be many reasons why your suspension requires attention, typical causes of suspension arm failure include:

1. A damaged ball joint
2. Car loses control because of the damaged to lower suspension parts
3. Worn out control arm bushings

For cars where the headlights move up and down, MOOG has created the M6 blind revert which is included with the following wishbones (VV-WP-3640 / VV-WP-3645 / VV-WP-4871 / VV-WP-4872).

Therefore, where Xenon headlights are attached, the height sensor can be fitted to the wishbone without having to buy other extra parts to complete the process.  

How to install the height sensor where Xenon headlights are fitted:

1. Screw the nut into the blind revert
2. Place the loaded revert into the pre-drilled hole in the wishbone
3. Tighten the nut to lock the rivet into place
4. Withdraw the nut from the rivet and the job is done

Some model variants of the above vehicles are fitted with auto levelling xenon headlights. The same wishbones can be used, although the system information that is required for adjusting the height level of the headlights comes from a sensor which is connected to the arm. Whilst the OE and MOOG wishbones have a locating hole, it doesn’t include the M6 thread rivet which is required for mounting the sensor to the arm.

Now, thanks to the M6 blind rivet, no other extra components need to be purchased to complete the installation.
