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 glare 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 glare oncoming traffic.

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

When to replace a suspension arm?

There are different problems that can appear with your car’s suspension arms. Here are 3 signs of bad control arms:

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

For the cars where the headlights move up and down, MOOG created the M6 blind revert 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 installed to the wishbone without having to buy other extra parts to complete the process.  

How to change a MOOG suspension arm where Xenon headlights are fitted

If you have car suspension problems here is how to fix them:

1. Screw a nut into the blind revert
2. Place the loaded revert into the pre-drilled hole in the wishbone
3. Tied 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 should be purchased to complete the installation!
