long-icon-xIs Your Suspension Failing? Ready to Order

How do I know if my 1987-1990 Pontiac Bonneville Air Suspension is failing?

Your 87-90 Pontiac Bonneville has served you well over the years, but if it is not meeting and maintaining its proper ride height then it may have a failed or leaking air suspension system. Left to run this way, other components will wear out and total failure will set in. Look for these common signs to diagnose a bad suspension before it’s too late. The most common is a sudden uneven height difference between different sides of the Bonneville. Typically the front will remain inflated while the rear end will sag; this is often described as “squatting” down low to the ground. Maybe there is leaning from one side to the other. Perhaps you hear the air compressor (it will be very noisy if it’s running too often), or maybe it has stopped working completely. The most obvious red flag is an illuminated suspension warning light on the instrument cluster. All of these signs point to a bad air suspension system. You have plenty of options- direct replacement, repair, replacement- but not all are equal.

What kind of suspension does my 1987-1990 Pontiac Bonneville have?

The 1987-1990 Pontiac Bonneville is built with the following suspension components:

1987-1990 Pontiac Bonneville Electronic Struts (x2)- a type of shock absorber; has metal tubing filled with gas-charged hydraulic fluid that is connected to the wheel of a vehicle in order to reduce the effects of vertical travel on a rough surface which controls the bounciness, and therefore comfort, of a vehicle. The 1987-1990 Pontiac Bonneville struts, while having coil-springs, use an electronic signal to stiffen or soften the dampening of the strut.

1987-1990 Pontiac Bonneville Shock Absorbers (x2)- a metal tubing filled with gas-charged hydraulic fluid that is connected to the wheel of a vehicle in order to reduce the effects of vertical travel on a rough surface which controls the bounciness, and therefore comfort, of a vehicle..

1987-1990 Pontiac Bonneville Height Sensors (x2)- a linkage located near each wheel of a vehicle with any electronic suspension that, either mechanically or electronically, constantly measures the height of the vehicle, and reports this information back to the control module so that the computer can identify if changes in height need to be adjusted accordingly. The ride height sensor is a moving part, and like all moving parts, they will eventually wear out.

1987-1990 Pontiac Bonneville Air Lines- tubes that run from a compressor (air suspension) to the air struts which carry pressurized air to the air bags components in order to adjust the height of the vehicle, respectively.

1987-1990 Pontiac Bonneville Control Module (x1)- a computer which is responsible for the operations of the air suspension system and maintaining the vehicle’s correct ride height.
