The 2007-2013 Acura MDX All-Wheel Drive equipped with Sport Package is built with the following suspension components:
2007-2013 Acura MDX Electronic Struts (x2)- (models with ADS electronic suspension only). Metal tubes filled with gas-charged hydraulic fluid that controls bouncing motion and dampens vibration caused by travel on rough road surfaces. These struts are equipped with a special Active Dampening System, which uses complicated electronic and magnetic devices to manipulate the dampening rate of the strut hundreds of times per second. The units rely on feedback from sensors and a suspension control module to function. The strut itself contains a perch for a steel coil spring which supports the weight of the vehicle. The entire unit itself is known as an electronic strut. These are much more expensive and complicated compared to a traditional passive (non-electronic) unit used on most vehicles.
2007-2013 Acura MDX Height Sensors (x4)- a linkage located near each wheel of the vehicle that constantly measures the height of the vehicle and reports this information back to the control module. The information is used to make adjustments in the internal valving of the struts and shocks to ensure a smooth ride on a variety of road surfaces. The ride height sensor is a moving part and they will eventually wear out.
2007-2013 Acura MDX Suspension Control Module - A computer that processes information provided by sensors located throughout the vehicle to make adjustments in the electronic portions of the suspension.
