Is Your Suspension Failing?
How do I know if my Air Suspension is failing?
Your 2005-2011 Cadillac STS has had a good run, but you may be noticing a failed or leaking air suspension. Look for these common signs of bad suspension. A suddenly noticeable uneven height difference between the left or right sides of the vehicle is an obvious one. A sagging rear or front end is another. Leaning, from any direction, is frequently seen. An overall squatting appearance in your Cadillac STS indicates a necessary repair. Other symptoms include an illuminated suspension warning light or message on the instrument panel, or an air compressor that has ceased working.
What kind of suspension does my have?
2005-2011 Cadillac STS Electronic/Magnetic Ride Control 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 Cadillac Deville’s struts, while having coil-springs, use an electronic signal to stiffen or soften the dampening of the strut. Some models came with Magnetic Ride Control, which use polarized particles within the hydraulic fluid to either make the ride softer or more firm based on the electrical impulse sent from the suspension control module.
2005-2011 Cadillac STS Coil Springs (x2)- Coil springs hold the vehicle up but be careful, they are rated for and designed to work with the rest of the suspension system, so when you change air shocks to passive shocks, then you will need a different rated coil spring that works well with the new type of shocks.
2005-2011 Cadillac STS Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicle’s correct ride height.

Read what customers like you thought of our product.
Searched our local warehouses, auto stores, even AC Delco dealer, and was unable to get a proper front strut for the STS. Found Strutmasters on YouTube and contacted them by phone. Spoke with Darrell, who is now my favorite suspension specialist! I would definitely recommend Strutmasters and Darrell. Their prices are unmatchable! Their parts are made in the USA, which matters to me, and their service is super fast!
Will be happy to write another glowing review after this weekend, when I receive and install my new front struts!!!
Thanks again to Darrell for taking the time to talk with me and share your expertise! I’ll definitely be a return customer!
