BREAKScheck your break pad or also could be rotors.most likely the rubber bushings are too dry on the suspension components
Press on all four corners of the car. Look for how long the car bounces and listen for the squeak. It could be a shock or strut, or in older vehicles a worn pad between leaf springs.
If you're referring to the suspension warning light on your car dashboard, the best way to address it is to have your suspension system inspected by a qualified mechanic. The light may indicate issues with the suspension that could affect the safety and performance of your vehicle. Ignoring it could lead to further damage or unsafe driving conditions.
Could be coil spring or air bag spring system. You have to look.
Agriculture. It is designed for the purpose.
It could be the shocks/struts or something in the steering system...have it checked out.
Most likely one of the bushings in the suspension moving a bit when you hit a bump, track it down and tighten it if you can. also check the shocks they will squeak when going bad
It could be badly out of balance, or it could have a "flat spot" from broken cords inside the tire. And it may not be the tire at all - it could be suspension system parts.
"Service Ride Control", which could be bad struts or air ride suspension system (or both).
There is no air valve for the rear air suspension as it is controlled by an auto-leveling system unless of course you change to manual fill air shocks then it could be anywhere.
If the squeeling is coming from the tires, then the problem is most likely a misaligned front end. If the squealing is coming from the engine, then the problem would be in the power steering system.
Because they are faulty system-engineering could be compressor located under right frond fender, could be a fuse, could be wires on top of suspension are broken --this is why the 2000-2005 Mercedes are crappy
